In a 100 m race, A can give B a start of 10 m and can give C a start of 28 m. In the same race, B can give C a start of:

18 m

20 m

27 m

9 m

Answer : Option B

Explanation :

A: B = 100: 90
And A: C = 100: 72

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

∴ B can give C a start of 20 m.
