(#M40002765) TCS QUESTION Keep an EYE

A hare and a tortoise have a race along a circle of 100 yards diameter. The tortoise goes in one direction and the hare in the other. The hare starts after the tortoise has covered 1/3 of its distance and that too leisurely. The hare and tortoise meet when the hare has covered only 1/4 of the distance. By what factor should hare increase its speed so as the win the race?
(a) 4
(b) 3
(c) 12
(d) 5

Solution

Total circumfrance = pie*diameter
tortoise has covered = 100pie/3
remaining distance = 200pie/3
1/4th of total distance = 25pie
let the velocity of tortoise = u and that of hare =v
on time comparison we get
125pie/3u = 25pie/v
5v=3u so v=3u/5

now for remaining journey time taken by tortoise = 25pie/u
so velocity of hare to make a tie = 75pie u / 25pie
=3u
so 3u/3u/5 = 5 times answer
