Questions and Answers

Q 1 - A can run 100m in 27 sec. and B in 30 sec. A beat B by

A - 9m

B - 10m

C - 11m

D - 12m

Answer : B

Explanation

Distance covered by B in 3 sec. =(100/30*3) m = 10m 
∴ A beats B by 10m.

Q 2 - A can run 20 m while B runs 25 m. In a km race, B beats A by:

A - 125m

B - 200m

C - 225m

D - 250m

Answer : B

Explanation

In a 25m race, B beats A by 5 m.
In a km race , B beats A by (5/25*1000) m = 200m

Q 3 - In a 100m race, A can beat B by 25m and B can beat C by 4m. In the same race, A can beat C by

A - 29m

B - 21m

C - 26m

D - 28m

Answer : D

Explanation

A :B = 100:75  and B :C = 100:96
∴ A :C = (A/B * B/C ) = (100/75*100/96 ) = 100/72 = 100:72
So, A  beats C by (100-72) m = 28m

Q 4 - In a 100m race, A can give B 10m and C 28m. In the same race, B can give C:

A - 18m

B - 20m

C - 22m

D - 24m

Answer : A

Explanation

A : B :C = 100:90:72
∴      B:C = 90/72    =(90* 100/90)/(72*100/90) = 100/80  = (100:80)
∴  B can give C 20 m.

Q 5 - A runs 7/4 times as fast as B. if A gives B a start of 60m , how far must the winning post be in order that A and B reach it at the same time ?

A - 140m

B - 105m

C - 80m

D - 45m

Answer : A

Explanation

Ratio of the rates of A and B = 7:4
 3m are gained by A in a race of 7m .
60m  are gained by A in a race of (7/3*60)m =  140m.

Q 6 - A and B take part in a 100m race. A runs at 5km/hr. A gives B a start of 8m and still beats him by 8 sec. B?s speed is:

A - 5.15 km/hr

B - 4.15 km/hr

C - 4.25 km/hr

D - 4.14 km/hr

Answer : D

Explanation

A's  speed  =(5*5/18) m/s = 25/18m/s.
Time taken by A to cover 100m  = (100* 18/25) sec.  =72 sec.
∴    B covers 92 m in (72+8) sec.= 80 sec.
∴ B's speed = (92/80)m/sec. = (92/80* 18/5) km/hr =  4.14km/hr

Q 7 - At a game of billiards, A can give B 15 points in 60 and A can give C 20 in 60. How many can B give C in a game of 90 ?

A - 10 points

B - 12 points

C - 14 points

D - 16 points

Answer : A

Explanation

A: B :C = 60:45: 40
 ∴  B:C = 45/40 =9/8 = 9*10/8*10 = 90/80
Thus , if B score 90 points , then C score 80 points.
B can give C 10 points in a game of 90.
