Example 2

Ghosh Babu took voluntary retirement in Dec. 1991 and received a certain amount of money as retirement benefits. On Jan 1, 1992, he invested the entire amount in shares. At the end of the month, he sold all his shares and realised 25% profit. On Feb 1, he reinvested the entire amount in shares which he sold at the end of the month at a loss of 20%. Again, he invested the entire amount on Mar 1 in a new company. At the end of the month, he sold the new company to a friend and realised a profit of 20% in the process. He invested the entire amount in shares on Apr 1, which he sold at the end of the month for Rs. 1,08,000 incurring a loss of 10%.

1. What is the amount of retirement benefits received by Ghosh Babu?
a) Rs. 1,08,000
b) Rs. 1,25,000
c) Rs. 1,20,000
d) Rs. 1,00,000

2. The percentage profit received by Ghosh Babu between Jan 1 and Apr 30 is:
a) 8.00%
b) 15.00%
c) – 10.00%
d) None of these

3. The amount of loss incurred by Ghosh Babu based on his operation in Apr 1992 is:
a) Rs. 25,000
b) Rs. 12,000
c) Rs. 20,000
d) Rs. 8,000

4. The maximum amount invested by Ghosh Babu in any one month was in:
a) January
b) February
c) March
d) April

Answers:
1. d Let the amount received by Ghosh Babu in Dec. 1991 be Rs. x, as retirement benefits:
Therefore, investment in the month of Jan 1992 = 100
Profit of 25% at the end of Jan 1992.
Hence, investment in the month of Feb 1992 = 125
Loss of 20% at the end of Feb 1992
Hence, investment in the month of March 1992 = 100
Profit of 20% at the end of March 1992
Hence, investment in the month of April 1992 = 120
Loss of 10% at the end of April 1992
Therefore the amount left at the end of April 1992 = 108
Amount at the end of April 1002 = Rs. 1,08,000
Therefore, simply equating figures, he would have started with Rs 1,00,000

2. a % Profit between Jan 1 and Apr 30 = (1.08x – x/x) X 100

3. b Investment in the month of April = Rs. 1,20,000
Amount received at end of April = Rs. 1,08,000
Therefore, Loss = Rs. 12,000

4. b Maximum amount invested by Ghosh Babu is in the month of February = Rs. 1,25,000

Solutions

S1. Ans.(b)

Sol. 200 million = 20% of population

⇒ Population = 200 × 5 = 1000 million = 100 crore

 

S2. Ans.(b)

Sol. 2004 population = 1000 million

Population in 2008 or after 4 years = 560 × 2 = 1120 million

∴ Growth rate = (120 × 100)/(1000 × 4) = (12/4)% = 3% per annum simple growth rate.

 

S3. Ans.(c)

Sol. Hotel users in 2004 = 200 million

Hotel users in 2008 = 560 million

∴ Growth in percentage =(560 – 200)/200=360/200=180%

 

S4. Ans.(a)

Sol. Total revenue in 2004 = 50 billion

Total revenue in 2008 = 150 billion

∴ Growth in percentage =(150 – 50)/50×100=100/50=200%

 

S5. Ans.(d)

Sol. By 2008 half or 50% of the India population will be using hotels.

We do not have any information about 2007. Hence the data is inadequate.

 

S6. Ans.(b)

Sol. Born 100 ⇒ 10 die at infancy

90 ⇒ 10 die till age 5

80 ⇒ 2/3×1/2×80 go to school

∴ Who attend Std. V =80×1/3×0.4=10.66%

 

S7. Ans.(d)

Sol. Number of child labourers in India =(90×1/15)crore = 6 crore

 

S8. Ans.(a)

Sol. Out of 100 born, 20 die by the age of 5.

Number of child labourers in Orissa and Bihar =1/3×80≅27

 

S9. Ans.(d)

Sol. Since we do not know how many children reach Std X, the answer cannot be found. Hence, option (d).

 

S10. Ans.(d)

Sol. Since we do not know the exact population of Kerala, Orissa and Bihar, the answer cannot be found.

 

S11. Ans.(c)

Sol. Number of female literates =90×9/19×0.38=16.2 crore

Number of male literates =90×10/19×0.57 = 27 crore

∴ Total literates = 16.2 + 27 = 43.2 crore

 

S12. Ans.(c)

Sol. Total illiterates in India = 90 – 43.2 = 46.8 crore

∴ Number of illiterates in Orissa and Bihar =1/3×46.8 = 15.6 crore

  1. Kartik, Bhuvan and Sid entered into a partnership and invested Rs 13,000, Rs 16,000 and Rs 19,000 respectively. After 7 months, Kartik and Bhuvan added Rs 1,000 and Rs 5,000 respectively while Sid withdrew Rs 5,000. If at the end of year their annual profit is Rs 43,160, find the total profit share of Kartik and Sid.
    A) Rs 28,030
    B) Rs 27,190
    C) Rs 26,830
    D) Rs 28,420
    E) Rs 27,040

    View Answer
      Option E
    Solution
    :
    Karti : Bhuvan : Sid
    13000*7 + 14000*5 : 16000*7 + 21000*5 : 19000*7 + 14000*5
    23 : 31 : 29
    So required share = (23+29)/(23+31+29) * 43160 = Rs 27,040
  2. Megha, Isha and Rani entered into a partnership by investing Rs 20,000, Rs X, and Rs 22,000 respectively for 6 months, 8 months and 10 months respectively. If Isha earns a profit of Rs 16500 out of a total profit of Rs 44,550, find the total investment done by all three.
    A) Rs 47,000
    B) Rs 25,000
    C) Rs 54,000
    D) Rs 39,000
    E) Rs 67,000

    View Answer
    Option E
    Solution:

    Megha : Isha : Rani
    20000*6 : X*8 : 22000*10
    30000 : 2X : 55000
    15000 : X : 27500
    So X/(15000+X+27500) * 44550 = 16500
    Gives X/(15000+X+27500) * 270 = 100
    Solve, X = 25,000
    So total investment = 20+25+22 = 67,000
  3. Kamya, Prisha and Tisha started a business by investing Rs X, Rs (X+400) and Rs (X-200). If after the end of year, total share of profit of Kamya and Tisha is Rs 8100 out of a total profit of Rs 13,500, find the profit share of Prisha.
    A) Rs 6100
    B) Rs 5400
    C) Rs 5100
    D) Rs 6600
    E) Rs 5500

    View Answer
    Option B
    Solution
    :
    Kamya : Prisha : Tisha
    X : (X+400) : (X-200)
    So (X+X-200)/(X + X+400 + X-200) * 13500 = 8100
    Solve, X = 1600
    So ratio of profit share is
    1600 : 2000 : 1400 = 8 : 10 : 7
    So profit share of Prisha = 10/25 * 13500 = Rs 5400
  4. Preeti, Anu and Aarti entered into a business. Preeti invested Rs 2500 for some months, Anu invested Rs 3000 for 2 more months than Preeti and Aarti invested Rs 3500 for 3 months less than Anu. If Anu got Rs 8400, out of a total profit of Rs 19,000, then Aarti invested her money for how many months?
    A) 3 months
    B) 5 months
    C) 4 months
    D) 6 months
    E) 2 months

    View Answer
    Option C
    Solution
    :
    Preeti : Anu : Aarti
    25000*x : 3000*(x+2) : 3500*(x-1)
    5x : 6(x+2) : 7(x-1)
    So (6x+12)/(5x + 6x+12 + 7x-7) * 19000 = 8400
    Solve, x = 5
    So Aarti invested money for 4 months

Directions (5-7): A, B and C started a business by investing Rs 800, Rs 1600 and Rs 2000 respectively. After a quarter they invested amounts in a ratio 1 : 4 : 2. After another quarter, they invested amounts in ratio 3 : 2 : 3.In the last quarter the ratio of investments was same as in 2nd quarter. Also in the last quarter, the respective amounts of A, B and C was double than the respective amounts invested in 2nd quarter. The total investment of C before 4th quarter was Rs 1400 more than that of A during same duration. Also ratio of B’s share in profit to total profit at the end of year was 66 : 153.

  1. Find the total investment of A, B and C.
    A) Rs 10,200
    B) Rs 11,300
    C) Rs 9,800
    D) Rs 10,080
    E) Rs 11,090

    View Answer
    Option A
    Solution
    :
    Quarters means 3 months each
    Ratio of investments in 2nd quarter – 1 : 4 : 2, so let amounts – x, 4x, 2x
    Ratio of investments in 3rd quarter – 3 : 2 : 3, so let amounts – 3y, 2y, 3y
    In last quarter, respective amount is double then in 2nd quarter, so amounts – 2x, 8x, 4x
    In the last quarter the ratio of investments was same as in 2nd quarter. —  this is not required to solve question.
    Given:
    (2000 + 2x + 3y) = 1400 + (800+x+3y)
    Solve, x = Rs 200
    Now ratio of profit share —A : B : C is
    800*3 + x*3 + 3y*3 + 2x*3 : 1600*3 + 4x*3 + 2y*3 + 8x*3 : 2000*3 + 2x*3 + 3y*3 + 4x*3
    3 gets cancelled, gives
    (800+3x+3y) : (1600+12x+2y) : (2000+6x+3y)
    Put x = 200 gives
    1400+3y : 4000+2y : 3200+3y
    Now given
    (4000+2y)/(1400+3y + 4000+2y + 3200+3y) = 66/153
    (2000+y)/(4300+4y) = 22/51
    Solve, y = Rs 200
    So now the total investment is—(800+3x+3y) + (1600+12x+2y) + (2000+6x+3y) = (4400 + 21x + 8y)
    put x = 200, y = 200, total investment = Rs 10,200
  2. If they respectively had invested same amounts in each quarter after quarter 1 which is equal to their respective investments in quarter 1, then what would be the profit of A at the end of year out of a total profit of Rs 19,350?
    A) Rs 2510
    B) Rs 3320
    C) Rs 2560
    D) Rs 3150
    E) None of these

    :
    800, 1600, 2000 as it is for 3 months, and then for next 9 months x, 4x and 2x
    So ratio of profit share – A : B : C is
    800*3 + 200*9 : 1600*3 + 800*9 : 2000*3 + 400*9
    7 : 20 : 16
    So profit share of A = 7/43 * 19350 = Rs 3150
  3. If the respective investments in third quarter was changed and this was in ratio 2 : 4 : 1 (other investments being the same), then what would be the total investment of all three in third quarter, if the average investment of all A B and C was Rs 3100 for whole year?
    A) Rs 700
    B) Rs 800
    C) Rs 500
    D) Rs 900
    E) None of these

    Option A
    Solution
    :
    New investments – 3z, 2z, and 2z
    Investment of A = (800+3x+2z), B = (1600+12x+4z) and C =(2000+6x+1z)
    Put x = 200
    A = 1400+2z, B = 4000+4z, C = 3200+1z
    Now given (1400+2z + 4000+4z + 3200+1z)/3 = 3100
    Solve, z = Rs 100
    So total investment for quarter 3 = 2z+4z+z = 7z = Rs 700

Directions (8-10): A, B and C started a business. They invested amounts in the ratio 1 : 3 : 2 respectively for 8 months. After this they invested amounts in ratio 2 : 3 : 4 respectively for 4 months. The average investment of A and B is Rs 2800 while average investment of B and C is Rs 3800.

  1. Find the total investment of C?
    A) Rs 4000
    B) Rs 5000
    C) Rs 6000
    D) Rs 4500
    E) Rs 3500

    Option A
    Solution
    :
    A : B : C is
    x*8 + 2y*4 : 3x*8 + 3y*4 : 2x*8 + 4y*4 gives (2x+2y) : (6x+3y) : (4x+4y)
    Given::
    (x+2y+3x+3y)/2 = 2800
    4x+5y = 5600
    Also (3x+3y+2x+4y)/2 = 3800
    5x+7y = 7600
    Solve both equations, x = 400, y = 800
    So total investment of C = (2x+4y) = Rs 4000
  2. If B’s investment for both the terms (4 months and 8 months) was swapped, then find the total profit share of B and C if annual profit is Rs 46,200.
    A) Rs 45,600
    B) Rs 32,800
    C) Rs 43,600
    D) Rs 37,800
    E) None of these

    View Answer
    Option D
    Solution
    :
    B’s investment for 8 months = 3x = 3*400 = Rs 1200 and for 4 months = 3y = 3*800 = Rs2400
    Now swapped, means for 8 months = Rs 2400 and for 4 months is Rs 1200
    So now ratio of A : B : C is
    400*8 + 1600*4 : 2400*8 + 1200*4 : 800*8 + 3200*4
    2 : 5 : 4
    So required profit = (5+4)/(2+5+4) * 46200 = Rs 37,800
  3. If A’s share in annual profit is Rs 9030, find the total profit after a year.
    A) Rs 41,390
    B) Rs 45,150
    C) Rs 42,610
    D) Rs 46,240
    E) Rs 43,170

    View Answer
    Option B
    Solution
    :
    Ratio of profit share is
    (2x+2y) : (6x+3y) : (4x+4y)
    x = 400, y = 800
    So ratio becomes
    1 : 2 : 2
    So 1/5 * x = 9030
    Total profit = x = Rs 45,150
