Question

Ratio of speeds of ‘A’ and ‘B’ is 2:3, respectively. If they participate in a 450-metre race and ‘B’ gives ‘A’, ahead start of ‘m’ metres, then they finish the race at the same time. Find the value of ‘m’.

A 100 metres Correct Answer Incorrect Answer
B 160 metres Correct Answer Incorrect Answer
C 150 metres Correct Answer Incorrect Answer
D 190 metres Correct Answer Incorrect Answer
E None of these Correct Answer Incorrect Answer

Solution

Let the distance covered by ‘A’ in the time ‘B’ covers 450 metres be ‘x’ metres (x/450) = (2/3) Or, x = 300 So, m = 450 – 300 = 150 metres
