In a 100 m race, A can give B 10 m and C 28 m. In the same race B can give C:
18 m
20 m
27 m
9 m
Answer: Option
Explanation:

A : B = 100 : 90.

A : C = 100 : 72.

B : C = B x A = 90 x 100 = 90 .
A C 100 72 72

When B runs 90 m, C runs 72 m.

When B runs 100 m, C runs 72 x 100 m = 80 m.
90

B can give C 20 m.

How B give C 20? Is we simply check question the right answer is 18 because 28-10=18.

What is the meaning of A can give start of 10 meter?

Vichu said:   1 decade ago
A can give 10 means A can lead B by 10 meter. That's A can give a lead of 10 meter. Got t @Arun.

Melvin its just not distance calculation to simply difference the distance. Here change in velocity of the players maters. For example if you just subtract the distance means B and C are running in same velocity right?

If so how would B can beat C in the race in the beginning? Got t so there is a velocity change in players that's what you are calculating unstintingly.
