Question

This math question will make you think.
Three people, A, B, and C compete in a race. A beats B by 10 m. B beats C by 10 m. By how much did A beat C?
The answer is not 80 m.
Use those brains and give me an answer.

Answer 1

The answer vary for different races (i.e) 100 m, 200 m, 400 m and others
__________________________________________________________

Let Taking the first race,

A:B = 100:90

B:C = 90:80

So, A:C = 100/90 × 90/80 ⇒ 100:80

And so, the answer = 20 m (as (100-80) m the distance by which A beat C)
