Question

Ratio of speeds of ‘A’ and ‘B’ is 11:13, respectively. If they participate in a 130-metre race and ‘B’ gives ‘A’, a head start of ‘m’ metres, then they finish the race at the same time. Find the value of ‘m’.

A 20 metres Correct Answer Incorrect Answer
B 25 metres Correct Answer Incorrect Answer
C 10 metres Correct Answer Incorrect Answer
D 12 metres Correct Answer Incorrect Answer

Solution

Let the distance covered by ‘A’ in the time ‘B’ covers 130 metres be ‘x’ metres (x/130) = (11/13) Or, x = 110 So, m = 130 – 110 = 20 metres
