The Sum Of Three Numbers Is 98. If The Ratio Of The First To Second Is 2 :3 And That Of The Second To The Third Is 5 : 8, Then The Second Number Is?

Answer»

Let the three parts be A, B, C. Then,

A : B = 2 : 3 and B : C = 5 : 8 = 5 * 3/5 : 8 * 3/5 = 3 : 24/5

=> A : B : C = 2 : 3 : 24/5 = 10 : 15 : 24

=> B = 98 X 15/49 = 30.
