## Quantitative Aptitude Practice Questions for IBPS PO Prelims 2018:

1. Solve: (x – 7)2 + x2 = (x + 2)2

A. x = 2 or x = 8

B. x = 5 or x = 15

C. x = 6 or x = 16

D. x = 4 or x = 12

Explanation:

x2 - 2 (7 x) + 72 + x2 = x2 + 2(1 x) + 12

2 x2 -14 x + 49 = x2 + 2 x + 1

x2 - 16 x + 48 = 0

(x - 4)(x - 12)=0

x - 4 = 0 or x - 12 = 0

x = 4 or x = 12

2. Find the approximate value of 1204 x 4.876 – 30.091

A.7200

B.9500

C.6950

D. 5950

Explanation:

As the options are far from each other, we can approximately do the calculations and find the approximate answer for these approximation questions.

Approximate Calculation:1200 x 5 – 30 = 5970

Therefore, we select option D; 5950 as it is approximately close to 5970.

3. 15, 22.5, 33.75, ? , 75.9375 which number replaces the '?' symbol

A. 47.345

B. 50.625

C. 51.225

D. 53.375

Explanation:

Multiply each number in the series with the 1.5. Hence, 33.75 * 1.5 = 50.625

4. A can do a piece of work in 6 days. B can do it in 7 days. With the assistance of C, they completed the work in 3 days. Find in how many days can C alone do it?

A. 32 days

B. 35 days

C. 38 days

C= 1/3-1/6-1/7 = 1/42 => 42 Days

5. Answer these questions based on the following pie charts :

a. The Tax burden in 1991-92 was higher than that in 1990-91 by

A. 45%

B. Rs. 5.5 lakh

C. 30%

D. Rs. 3.9 lakh

Explanation:

Tax in 1990-91 = 12% of 130 = Rs. 15.6 lakh

Tax in 1991-92 = 9% of 160 = Rs. 11.7 lakh

Hence, difference = (15.6 - 11.7) = Rs. 3.9 lakh

b. The operating profit in 1991-92 increased over than in 1990-91?

A. 22%

B. 23%

C. 24%

D. 25%

Explanation:

Percentage increase = (160 - 130) x(100/130)

= 300/13 = 23%

c. The retained profit in 1991-92, as compared to that in 1990-91 was:

A. higher by 2.5%

B. higher by 1.5%

C. lower by 2.5%

D. lower by 1.5%

Explanation:

Retained profit in 1990-91 = (25% of 130) = Rs. 32.5 lakh

Retained profit in 1991-92 = (20% of 160) = Rs. 32 lakh.

Hence, percentage change in retained profit.

= (32.5 - 32)/32.5 = 1.5% lower.

d. The equity base of these companies remained unchanged. Then, the total dividend earning by the shareholders in 1990-91 is:

A. Rs. 10.4 lakh

B. Rs. 9 lakh

C. Rs. 12.8 lakh

A. Rs. 500

B. Rs. 1500

C. Rs. 2000

D. None of these

Explanation:

Let the shares of P, Q, R, and S be Rs. 5x, Rs. 3x, Rs. 4x and Rs. 2x respectively.

Then,  4x - 2x = 1000

x = 500.

Q's share = Rs. 3x = Rs. (3 x 500) = Rs. 1500.

7. The compound interest on Rs.30000 at 7% per annum is Rs.4347. The period is

A. 5 years

B. 3 years

C. 2 years

D. 4 years

Explanation:

Amount = Rs.(30000+4347) = Rs.34347

let the time be 'n' years

Then, 30000 (1+7/100)n = 34347

= 34347/30000 = 11449/10000 = (107/100)2

n=2 years

8. A thief is noticed by a policeman from a distance of 300 m. The thief starts running and the policeman chases him. The thief and the policeman run at the rate of 10 km per hour and 11 km per hour respectively. What is the distance between them after 10 minutes?

A. 130 m

B. 133 m

C. 120 m

D. 123 m

Explanation:

Relative speed of the thief and policeman  =  (11 – 10) km/h = 1 km/h

Distance covered in 10 minutes  = (1/60) x 10 km   = 1/6 km = 167 m

Therefore, Distance between the thief and policeman = (300 – 167) m = 133 m.

9. A pump can fill a tank with water in 2 hours. Because of a leak, it took 2 hours to fill the tank. The leak can drain all the water of the tank in:

A. 14 h

B. 15 h

C. 16 h

D. 17 h

Explanation:

Work done by the leak in 1 hour =(1/2) - (3/7) = 1/14.

∴ Leak will empty the tank in 14 h.

10. Find the area of a parallelogram with base 22 cm and height 14 cm.

A. 262 cm2

B. 308 cm2

C. 192 cm2

D. 131 cm2

Explanation:

Area of a parallelogram = base * height = 22 * 14 = 308 cm2
