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 - In a 300m race, A beats B by 15 meters or 5 sec. A?s time over the course is

A - 90 sec

B - 95 sec

C - 100 sec

D - 105 sec

Answer : B

Explanation

15m are covered by B in 5 sec.
300 m are  covered by B in (5/15*300) sec. = 100 sec.
Time taken by A =(100-5) sec.=   95 sec.

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 500 m race, the ratio of the speeds of A and B is 3:4. A has a start of 140m. A wins by:

A - 10m

B - 20m

C - 40m

D - 60m

Answer : B

Explanation

.To reach  the winning  post A has to cover (500-140)m = 360m
 While A covers 3 m , B covers 4 m.
While A  covers 360m , B covers (4/3*360)m = 480m
∴    A wins by 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 - In a race of 200 m, A can beat by 31m and C by 18m. In a race of 350m, C will beat B by

A - 22.75m

B - 18m

C - 25m

D - 32m

Answer : C

Explanation

A :B:C =  200: 169: 182
 ∴      C/B = (182*350/182)/ (169*350/182) =  350/325 
Thus  when C covers  350m,  B covers 325m.
∴ C beats B by 25 m .

Q 7 - In a game of 100 points , A can give B 20 points and C 28 points. Then, B can give C:

A - 8 points

B - 10 points

C - 12 points

D - 14 points

Answer : B

Explanation

A:B:C = 100:80:72
 ∴     B:C = 80/72 =10/9 =100/90
If B scores 100, then C  scores 90.
Hence, B can give C 10 points.
