42Railway RRB : Model paper 1
When B covers 960 m, C covers 936 m
When B covers 1000 m, C covers [
× 1000] m = 975 m
So, B can give C a start of (1000 - 975) or 25 m
41. Option A
Ratio of the speeds of A and B =
: 1 = 5 : 3
Thus, in a race of 5 m, A gains 2 m over B.
2 m are gained by A in a race of 5 m.
80 m will be gained A in a race of [
× 80] m = 200 m
So, winning post is 200 m away from the starting point.
42. Option D
A : B = 100 : 90 and A : C = 100 : 87
=
×
=
×
=
When B runs 30 m, C runs 29 m
When B runs 180 m, C runs [
× 180] m = 174 m
So, B beats C by (180 - 174) m = 6 m
