In a race of 100 m, A beats B by 4 m and A beats C by 2 m. By how many metres (approximately) would C beat B in another 100 m race assuming C and B run with their respective speeds as in the earlier race ?

- A2
- B2.04
- C2.08
- D3.2
Explanation
vB/vA = 96/100 and vC/vA = 98/100; when C runs 100 m, B runs 100 x 96/98 = 97.96 m, so C beats B by about 2.04 m. Hence option (b).
