In a 300-metre race, ‘Aman’ beats ‘Bhanu’ and ‘Charu’ by 30 metres and 60 metres, respectively. If ‘Bhanu’ and ‘Charu’ ran a 180 metre race, then ‘Bhanu’ will beat ‘Charu’ by:

ATQ,

Distance covered by ‘Bhanu’ in the time taken by ‘Aman’ to cover 300 metres = 300 – 30 = 270 meters

Distance covered by ‘Charu’ in the time taken by ‘Aman’ to cover 300 metres = 300 – 60 = 240 meters

Since, the time taken is same in this case, the ratio of speeds of ‘Bhanu’ and

‘Charu’ will be same as the ratio of distances.

Ratio of speeds of ‘Bhanu’ and ‘Charu’ = 270 : 240 = 9 : 8

So, in a 180-metre race, ‘Bhanu’ will beat ‘Charu’ by

180 – (180 × 8/9) = 180 – 160 = 20 metres
