In a 100 m race, A can give B 10 m and C 28 m. In the same race B can give C:
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 | ![]() |
= 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?

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.
