OPtion

1) 75
2) 25
3) 100
4) 40
5) 125
6) 350
7) 150
8) 450
9) 175
10) None of these

Solution

When A covers 400m B Covers 280m
When A Covers 400m C covers 320

A : B = 400 : 280
A : C = 400 : 320

C/B = (C/A*A/B) = (320/280) = 320:280
When C covers 320 m, B covers 280 m.
When C covers 1000 m, B covers (280/320)*1000)m = 875m
Therefore, C beats B by (1000 - 875) m = 125 m.
