Q1. Option A

Distance in plains = 60% of 150km = 60 x 1.5 = 90km

Distance in hills = 24% of 150km = 24 x 1.5 = 36km

Distance in desert = 16% of 150km = 16 x 1.5 = 24km

Total distance in plains & hills = 90+36 = 126km

Total time in plains & hills = 2.25 + y

ATQ, 42km/hr = 

42 (2.25 + y) = 126

94.5 + 42y = 126

y = 31.5/42 = 0.75 hrs

Avg. speed of man in hills = 36km / (0.75hrs) = 144/3 = 48 km/hr

 

Q2. Option B

If y = 0.75 hrs, x = 4.5 – (2.25 + 0.75) = 1.5 hrs

Then, time spent on work in plains = 42% of 2.25 = 0.945 hrs

Time spent on work in hills = 10% of 0.75 = 0.075 hrs

Time spent on work in desert = 2% of 1.5 = 0.030 hrs

Total time spent on work = 0.945 + 0.075 + 0.030 = 1.05 hrs

Time (in minutes) = 1.05 x 60 = 63 minutes

Questions he can answer in 63 minutes = Quotient of ( 63 / 5 )

= 12 questions

His pay = (12 questions) x (₹75) = ₹ 900

Savings = 12.5% of 900 = ₹112.5    

 

Q3. Option C
Distance in plains = 60% of 150km = 60 x 1.5 = 90km = a (say)

Distance in hills = 24% of 150km = 24 x 1.5 = 36km = b (say)

Distance in desert = 16% of 150km = 16 x 1.5 = 24km = c (say)

Given,

(Expense in landscape)

Expense in desert = (90 x 87000)/174 = 90000/2 = ₹45,000

Expense on meals = 40% of 45000 = 450 x 40 = ₹18,000

 

Q4. Option D

Distance in plains = 60% of 150km = 60 x 1.5 = 90km

Distance in hills = 24% of 150km = 24 x 1.5 = 36km

Distance in desert = 16% of 150km = 16 x 1.5 = 24km

So, ATQ, m% of 24 = 36

Or, m = (36 x 100)/24 = 1.5 x 100 = 150% …(1)

And, n% of 90 = 24

Or, n = (24 x 100)/90 = 24 x 0.9 = (80/3)% …(2)

Required ratio = [150 + (80/3)] : [150 – (80/3)]

= (450+80) : (450-80) = 530 : 370 = 53 : 37

 

Q5. Option E

Given that, x – y = 0.75

And, x + y = 4.5 -2.25 = 2.25

Adding them, 2x = 3 or, x = 1.5hrs and y = 2.25 – x = 0.75 hrs

Distance in hills = 24% of 150km = 24 x 1.5 = 36km = a (say)

Distance in desert = 16% of 150km = 16 x 1.5 = 24km = b (say)

Swapping a and b, while time remained same,

Distance in hills = b = 24km in time taken in desert = x = 1.5hrs

Distance in desert = a = 36 km in time taken on hills = y = 0.75hrs

Avg. speed of B on hills = 24km/ 1.5hrs = 16km/hr

Avg. speed of B in desert = 36km/ 0.75hrs = 48km/hr

Required ratio = 16km/hr : 48 km/hr = 1 : 3

 

Q6. Option B

 

Q7. Option A

 

Q8. Option B

Total units sold by companies A, B and C = (500 + 700 + 200) = 1400

Total units produced by companies A, B and C = 800 + 1000 + 400 = 2200

 

Q9. Option E

 

Q10. Option E

The total units produced by companies C, D and E = 400 + 700 + 900 = 2000 units

The total units sold by companies B, C and F = 700 + 200 + 200 = 1100 units
