Quants Quiz Week 4

1. Sarita is twice as old as her son, Varun. If 20 years ago, the age of Sarita was 10 times the age of her son Varun, what is the present age of Sarita ?

a) 38 years

b) 40 years

c) 43 years

d) 45 years

Solution: 45 years

Let the age of son = X years

Age of mother would be =2X

As per question 20 years ago;

10 (X -20) = 2X – 20

10X – 200 = 2X – 20

10X – 2X= – 20 + 200

8X = 180

X= 22.5 years

∴Age of mother = 22.5 * 2 = 45 years

2. Abhi does half as much as work as Bunty in 1/6 of the time taken by Bunty. Together they can complete the work in 10 days. Bunty alone can complete the work in how many days?

a) 20 days

b)30 days

c) 40 days

d) 50 days

Solution: 40 days

Let Bunty does 1 work in x days

Then, Abhi  does [1/2] work in x/6 days

To do 1 unit work, Abhi will take x/3 days

That means time ratio of Abhi: Bunty = x: x/3

Or time ratio = 1: 1/3

Or time ratio = 3: 1

As we know that the efficiency ratio is inversely proportional to time ratio

i.e., Efficiency ratio of A: B = 1: 3

ATQ,

(A+B) = 10 days

Total work = days* efficiency of (A+B)

Or, total work = 10 * 4 = 40 units

i.e., B can finish the work in = total work/ efficiency of B

So, B can finish the work in 40/1 = 40 days.

3. A boatman can row a boat at a speed of 20 km/hr in still water. If the speed of the stream is 5 km/hr, in what time the boatman can row a distance of 75 km downstream?

a) 1.5 hours

b) 2 hours

c) 2.5 hours

d) 3 hours

Solution: 3 hours

Speed of boat = 20 km/hr

Speed of stream = 5 km/hr

∴ Speed downstream = 20 + 5= 25 km/hr

Required Time = Apti Boat and streams 32 = Apti Boat and streams 33 = 3 hours

4. Saikat bought an article at 25% less of the marked price and sold it at 15% more than the marked price. Find the profit earned by him.

a) 53.3 %

b) 55%

c) 57.3%

d) 52.3 %

Solution: 53.3 %

Let the marked price be Rs. 100

∵ C.P. = 100 – 25 = 75

And S.P. = 100+15 = 115

Profit (S.P – C.P.) = 115 – 75 =40

Profit % = (Profit /Cost Price) x 100

= (40/75)x100 = 53.3%

5. Find the value of √(12-√(12-√(12-√(12-…..n

a) 3

b) 2√2

c) 4

d) √6

Solution: 3

In case of the same type of root values, subtraction breaks the given number in a consecutive order, so the smallest number will be the answer.

i.e., the number is 12, and the consecutive order of six: 4*3, so the answer is 3.
