## How to solve Problems based on Ages

**Introduction:**

Today we are going to discuss on AGES this is quite easy when comparing other application sums and it take just few seconds to solve the question.

** And it carries 1 or 2 marks in the Prelims as well as in Mains**

**There are only 3 Types of problems in ages namely:**

**1.Finding Present Age**

**2.Finding Previous Age(Age before some years)**

**3.Finding Future Age(Age after Some years)**

## TYPE 1:

## BASED ON FINDING PRESENT AGE:

**1.The ages of Rahul and Amit are in the Ratio of 9:6.Their sum of the ages be 95.Find the age of Rahul?**

Rahul age=9X Amit Age=6X

Sum of their Ages be(9X+6X)=15X

Rahul’s age=95*(9/15)

** =57 years**

**2.Present Ages of Sameer and Anand are in the ratio of 5:4 respectively.Three years hence,the ratio of their ages will become 11:9 respectively.What is Anand’s Present age in years?**

Person | Present Year | After 3 Year |

Sameer | 5x | 5x+3=11 |

Anand | 4x | 4x+3=9 |

9(5X+3)=11(4X+3)

45X+27=44X+33

**X=6 **

**Anand’s Present Age=4*6=24Years**

**3.A father said to his son,”I was as old as you are at the present at the time of your birth”,If the father’s age is 38 years now,the son’s age is?**

Let the son’s present age be X,

Then,(38-X)=X

2X=38

**X=19 years**

**TYPE 2:**

**BASED ON EFFICIENCY:**

**1)A man is 24 years older than his son. In two years, his age will be twice the age of his son. The present age of his son is?**

Let Son’s Age=X

Man Age =24 + X

**After two years:**

24 + X+2=2(X+2)

26 + X=2x+4

**X=22 years**

**2)A is two years older than B who is twice as old as C.If the total of the ages of A,B and C be 27,then how old is B?**

A | B | C |

2X+2 | 2X | X |

(2X+2) +2X + X=27

5X+2=27 5X=25 X=5

B=2X, B=2*5

B=**10years.**

## How to solve Problems based on Ages Part-2

**INTRODUCTION:**

Problems based on Ages is the easiest topic in all the banking exams,and it is asked in Prelims and Mains Exam for 1 or 2 Mark.

**There are only 3 Types of problems in ages namely**

1.Finding Present Age

2.Finding Previous Age(Age before some years)

3.Finding Future Age(Age after Some years)

We had discussed how to solve problems based on ages in the previous article,Click here to view how to solve problems based on Ages

Note :

If they didn’t specify the age then consider the age to be X

### TYPE 1:

### FINDING AGE BEFORE SOME YEARS :

In this type we are going to assume the present age is X and to find the age before Y years then Age=**X-Y**

**1)Ganesh is 24 years younger than his Father Bholenath.3 years ago,Ganesh was 1/5 as old as his father was.What is Ganesh’s present age?**

Years | Bholenath | Ganesh |

Present | X | X-24 |

3 years Ago | X-3 | X-24-3=X-27 |

Before 3 years:

X-27=1/5(X-3)

5X-135=X-3

4X=132

**X=33**

**Ganesh’s Age =(33-24)=9 Years**

** 2.The ratio of ages of Amir and Salman is at present 3:4, 5 Years before that ratio was 2:3.What is the present age of Amir and Salman?**

Years | Amir | Salman |

Present Year | 3X | 4X |

5 years ago | 2 | 3 |

(3X-5)/(4X-5)=2/3 ⇒ **X=5**

** **Amir’s Present Age=**15years** and Salman’s Present Age=**20years**

**TYPE 2:**

**FINDING AGES AFTER SOME YEARS:**

Let the number of years be X and the age after Y years is **X+Y years**

**1.A person’s Present Age is two-fifth of the age of his mother. After 8 years, he will be one-half of the age of his mother. How old is the mother at present?**

Let the present age of the mother be **X years,**

Then, the present age of the son is 2/5(X) years.

[2/5(X)+8]=1/2[X+8]2(2X+40)=5(X+8)

**X=40**

**2.Ranjan’s and Anurag’s Age are in the ratio 4:5.4Years hence,their age ratio will become 5:6.What is Anurag’s present age?**

YEARS | ANURAG | RANJAN |

Present year | 5 | 4 |

After 4 year | 6 | 5 |

=

**X=4**

**Anurag’s Present Age=20 years**

a)16 b)20 c)25 d)30

**Alternate Method(Choosing from the option)**

Ratio’s are 4:5 and after 4 years 5:6

It is clear that Anurag age is a** multiple of 4** now And **after 4 yrs it is a multiple of 5**

### SHORTCUT METHOD:

**When two ratio’s and after/before some years are given**

**Formula**

**1.The age of Rahul and Amit are in the ratio of 8:7.After 10 years the ratio of their Ages will be 13:12.What is the difference in years between their ages?**

New Ratio Difference=13-12=1

Added number =10 years.

Difference between old and new ratio’s Cross Multiplication

=(8/7) * (13/12)

= (96-91)=5

Present Age=(1*10)/5 =** 2yrs**

Difference between their age =(8*2)-(7*2)=16years-14years=**2years**

__Age Aptitude Tricks__

__Type 1:__

**1) The ratio of Asha and Sushma are in ratio 3:4 after 8 year the ratio of their ages will be 7:8. What is difference in years between their ages?**

**Solution:**

8 years × (difference 8-7) / (7×4) – (8×3)

= 8 × 1 / 28-24

Difference =8/4 = 2

**2) 10 years ago ratio of ages of A and B was 3 : 1 and after 10 years the ratio of their ages become 2 : 1. Find the sum of present ages?**

**Solution:**

Given total years 10 and 10 so we take 20 years

20×1 / 1 = 20

A B

10 years ago 3×20 : 1 × 20

Present age 60+10 : 20+10

Sum = 100 years

**3) 5 years ago ratio of age A and B are 5 : 8 and after 5 years it will become 5 : 9 find present age?**

__Type 2:__

**1). Ratio between the ages of Mother (M) and her Daughter (D) 4 years ago was 19 : 5. If difference between ages of mother and daughter is 28 years what will be the ratio of their present age?**

**2). 3 years ago A was 4 times as old as B. After 18 years A age will exceed B’s age by 12 years. The ratio of present ages of A and B is?**

**3). Divya got married 6 years ago. Today her age is 1 ¼ times her age at the time of marriage. His son age is 1/10 times her age. Age of her son is.**

**(T) – Today Present Age Ratio**

**(M) – At the time of Marriage Age ratio **

__Type 3:__

**1). Five years ago the sum of the ages of Father and Son was 60 years. The ratio of present ages is 4 : 1. What is the present age of father?**

** Solution**:

Present age of F + S = 60 + 10 = 70

F : S

4 : 1 ( present age)

5 –> 70

1 –> 14

Present age of F = 14 × 4 = 56 years

__Type 4:__

**1). Sum of ages of father and son is 46 years. Seven years ago the product of their ages was 4 times the father age at that time. Find present age of father and son?**

**Solution:**

(F-7) ×(S-7) = 4 × (F –7)

S – 7=4

S = 11 years (present)

F = 35 years (present)

__Type 5:__

**1). Ratio of Arjun and Bhuvan age is 3 : 5. Ratio of Bhuvan and Cibi is 2 : 3. If Arjun is two fifth of Cibi what is Arjun’s age?**

No one’s age is given it can’t be determined

__Type 6:__

**1). The Average of 8 men is increased by 2 years when two of them whose ages are 21 and 23 are replaced by Two new men. The average of two new men is?**

** Solution**:

Thus in numerator there must be changed of 16 to change average age by 2

Increase 2 years = 8 × 2 = 16

Two men = 21 + 23 = 44

= 16 +44 = 60

Average 60/2 = 30 years

**2). The average age of family of 10 members is 20 years. If the age of youngest member of the family is 10 years then the average of the member of family just before the birth of youngest member was approximately?**

**Solution:**

Here number is not constant and notion of time too

Thus total age = 20 × 10 = 200

10 years ago = 200 (10 ×10)

= 200-100

= 100

Average = 100/9

**Best way to solve Age questions is to assume fixed period with which further conditions will be compared. For example taking 2000 as fixed year.**

## Application of this rule

### Example 1

Raman’s age after 15 years will be 5 times his age 5 years back. What is his present age ?

### Example 2

Rahul was 4 times old as his son 8 years back and he will be 2 times old as his son after 8 years. Calculate Rahul and his son’s age.

### Basic Concept for problems on ages :

**#1.** If the present age of ‘A’ is ‘x’ years, then

‘n’ years ago => Age of ‘A’ was (x-n) years.

‘n’ years after => Age of ‘A’ will be (x+n) years.

**#2.** In general, at the starting of the solution we have to assume the present age of one person. It is better to assume the present age = ‘x’ years.

**#3.** So I advise you to assume the age of the younger person = ‘x’ years.

**#4.** If the present age ‘A’ and ‘B’ are ‘x’ and ‘y’ years respectively, then

‘n’ years ago => Age of ‘A’ and ‘B’ were (x-n) and (y-n) years respectively.

‘n’ years after => Age of ‘A’ and ‘B’ will be (x+n) and (y+n) years respectively.

**#5.** The age difference between you and your friend is let’s suppose 6 years. And after 10 or 15 years this will be same, because clock will run equally for both of you. I hope you are getting what I am trying to say. : )

**Q 1.** Lina got married 8 years ago. Today her age is 9/7 time her age at the time of her marriage. At present her daughter’s age is 1/6 of her age. What was her daughter’s age 3 years ago? **(PNB MT 2009)**

**Explanation:**

Let’s assume present age of Lina = x yrs.

Hence, x = (x-8) * 9/7 => x=36 years.

So present age of daughter = 1/6 * 36 => 6 years.

3 years age of daughter = 6-3 = **3 years.**

**Q 2.** The age of Rahul and Amit are in the ratio of 8:7. After 10 years the ratio of their ages will be 13:12. What is the difference in years between their ages? **(UBI PO 2008)**

**Explanation:**

Lets assume the present age of Rahul and Amit = 8x and 7x

After 10 years,

(8x+10)/(7x+10) = 13/12

We get x=2 years.

So difference in age 8x – 7x = 16 – 14 = **2 years**.

**Shortcut:** We can use the below formula to find out value of ‘x’.

Here new ratio difference = 13-12 = 1 and added number = 10 (years)

Cross multiplication difference = 96 – 91 = 5

X = (1 * 10)/5 = 2 years. : )

**Q 3.** The ratio between the ages of Prahlad and Ramavtar is 3:5 and difference between their ages after 4 years will be 10 years. What is the present age of Prahlad?

**Explanation:**

Generally people starts assuming the present age as x and then adding +4 to get ages after 4 years and later solve it by making equations. But do you know that will consume a lot of you time and we all know time is the key to crack any exam.

So here by basic concept no. 5, as the age difference between you and your friend is let’s suppose 6 years. And after 10 or 15 years this will be same as 6 years.

Hence the ration of their ages is 3:5

It mean actual age will be 3x and 5x.

Now the difference between their age will be 3x-5x = 10 (given)

So we get x = 5 years.

Age of Prahlad = 3x = 3 * 5 = **15 years**.

**Q 4.** Ganesh is 24 years younger than his Father Bholenath. 3 years ago, Ganesh was 1/5 as old as his father was. What is Ganesh’s present age?

**Explanation:**

As per given 10 years, ratio between their age was Ganesh : Bholenath = 1x : 5x

Now Ganesh is 24 years younger than his father. It means their age difference will be 24 years.

Hence, 5x -1x = 24 years. => x= 6 years.

This age was 3 years ago so today Ganesh’s age will be 6 + 3 = **9 years.**

**Q 5.** The total age of Ram and Shyam is 10 years more than that of total age of Shyam and Mohan. Mohan is how many years younger than Ram? **(NABARD 2010)**

**Explanation:**

R + S = S + M +10 => R = M + 10 => M = R -10

Hence Mohan is **10 years** younger than Ram.

**Have a look at the following questions:-**

**Ex. 1: The age of the father 3 years ago was 7 times the age of his son. At present, the father’s age is five times that of his son. What are the present ages of the father and the son?**

**Ex. 2: At present, the age of the father is five times the age of his son. Three years hence, the father’s age would be four times that of his son. Find the present ages of the father and the son.**

**Ex. 3: Three years earlier, the father was 7 times as old as his son. Three years hence, the father’s age would be four times of his son. What are the present ages of the father and the son?**** **

**Ex. 4: The sum of the ages of a mother and her daughter is 50 yrs. Also 5 yrs ago, the mother’s age was 7 times the age of the daughter. What are the present ages of the mother and the daughter?**

**Ex. 5: The sum of the ages of a son and father is 56 yrs. After 4 yrs, the age of the father will be three times that of the son. What is the age of the son?**

**Ex.6: The ratio of the ages of the father and the son at present is 6: 1. After 5 years, the ratio will become 7 : 2. What is the present age of the son?**** **

**By the conventional method:-**

**Solution: 1.** Let the present age of son = x yrs

Then, the present age of father = 5xyr

3 years ago,

7(x – 3)= 5x – 3

Or, 7x – 21 =5x – 3

Or, 2x =18

x = 9 yrs

Therefore, son’s age = 9 years

Father’s age = 45 years

**Solution: 2. **Let the present age of son = x yrs

Then, the present age of father = 5x yrs

3 yrs hence,

4(x+3)= 5x+3

Or, 4x + 12=5x +3

x= 9yrs.

Therefore, son’s age = 9 yrs and father’s age = 45 yrs

**Solution: 3. **Let the present age of son = x yrs and the present age of father = y yrs

3 yrs earlier, 7(x – 3) = y – 3 or, 7x – y =18………….(i)

3 yes hence, 4(x+3) = y +3

Or, 4x +12 = y + 3 or, 4x – y = – 9 …………(ii)

Solving (1) & (2) we get, x = 9 yrs & y =45 yrs

**Solution: 4.** Let the age of the daughter be x yrs.

Then, the age of the mother is (50x – x)yrs

5 yrs ago, 7(x – 5) = 50 – x – 5

Or, 8x = 50 – 5 +35 = 80

x =10

Therefore, daughter’s age = 10 yrs and mother’s age = 40yrs

**Solution: 5. **Let the age of the son be x yrs.

Then, the age of the father is (56 – x) yrs.

After 4 yrs, 3(x+4) = 56 – x +4

Or, 4x =56 +4 – 12 = 48

x = 12 yrs

Thus, son’s age = 12 yrs.

**Solutions: 6. **

** Father : Son**

Present age = 6 : 1

After 5 yrs = 7 : 2

Son’s age =

Father’s age =

**Other Method:-**

**Solution: 1. **

Son’s age =

=9 yrs

and father’s age = 9 × 5 = 45 yrs.

Undoubtably you get confused with the above method, but it is very easy to understand and remember. See the following form of question.

**Question: t1 yrs earlier the father’s age was x times that of his son. At present the father’s age is y times that of his son. What are the present ages of the son and the father?**

**Formula**

**Solution 2: **Son’s age =

= 9yrs and father’s age = 9 × 5 =45 yrs

To make more clear, see the following form:

** ****Questions:** **The present age of the father is y times the age of his son. t2 yrs hence, the father’s age become z times the age of his son. What are the present ages of the father and his son?**

**Formula **

**Solutions.3:**

Son’s age =

= 9 yrs

To make the above formula clear, see the following form of question.

**Questions: t1 yrs earlier, the age of the father was x times the age of his son. t2 yrs hence, the age of the father becomes z times the age of his son. What are the present ages of the son and the father?**

**Formula **

**Solutions. 4:**

Daughter ‘s age =

Thus, daughter’s age = 10 yrs and mother’s age = 40 yrs** **

**Solutions. 5: **

Son’s age =

**Note : **Do you get the similarities between the above two direct methods? They differ only in sign in the numerator. When the question deals with ‘ago’, a +ve sign exixts and when it deals with ‘after’, a –ve sign exists in the numerator.

**Solutions. 6: **Then what formula comes?

Father : Son

Present age = x : y

After T yrs= a : b

Then, Son’s age =

And, Father’s age =

**Note:**

**1.** While evaluating the difference of cross-product, always take +ve sign.

**2.** Both the above direct formulas look similar. The only difference you can find is in the denominators. But it has been simplified as “difference of cross-products” to make it easier to remember. So, with the help of one formula only you can solve both the question.

**3.** We suggest you to go-through both the methods and choose the better of the two.
