by harsh.champ » Mon Feb 08, 2010 4:54 am
Two cyclists are travelling at a speed of 3 km/hr and 10 km/hr around a circular track. What should be the ratio of number of distinct points that they would meet on that track if they travel in the same direction first and in the opposite direction next?

(A)7 : 13
(B)3 : 10
(C)3 : 7
(D)30 : 13
(E)Cannot be determined

THe OA is A.
It takes time and effort to explain, so if my comment helped you please press Thanks button :)



Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.
