Question
A total of 444 chocolates are
distributed among P, Q, and R in the ratio 3:5:4. If the distribution were instead done in the ratio 1/2:1/3:2/5 , how many fewer chocolates would Q receive?Solution
ATQ, Given ratio = (1/2):(1/3):(2/5) = 15:10:12 Number of Chocolates actually received by ‘Q’ = 444 × (5/12) = 185 Number of Chocolates received by ‘Q’ according to the new ratio = 444 × (10/37) = 120 So, difference in number of Chocolates received by ‘Q’ = 185 – 120 = 65
