Rs. 730 were divided among Punith, Michael, Suresh in such a way that if Punith gets Rs. 3, then Michael gets Rs. 4 and if Michael gets Rs. 3.50 then Suresh gets Rs. 3. The share of Michael exceeds that of Suresh by Pick:	A) rs 30	B) rs 40	C) rs 70	D) rs 210	E) rs 310

Rationale: explanation : let a = punith , b = michael , c = suresh . a : b = 3 : 4 and b : c = 7 / 2 : 3 = ( 8 / 7 ) * ( 7 / 2 ) * ( 8 / 7 ) * 3 = 4 : ( 24 / 7 ) a : b : c = 3 : 4 : 24 / 7 = 21 : 28 : 24 . bs share = rs . [ 730 * ( 28 / 73 ) ] = rs . 280 . cs share = rs . [ 730 * ( 24 / 73 ) ] = rs . 240 . difference of their shares = 40 answer : b
Answer: B
