'A', 'B' and 'C' distributed Rs. 1440 among themselves
in the ratio 7:5:4, respectively. 'A' gave some amount to 'B' such that new amount with 'B' is thrice of that with 'A' now. Find the amount given by 'A' to 'B'.Solution
Amount received by 'A' = 1440 × (7/16) = Rs. 630 Amount received by 'B' = 1440 × (5/16) = Rs. 450 Let Amount given by 'A' to 'B' be Rs. 'x' According to the question, 3 × (630 - x) = 450 + x Or, 1890 - 3x = 450 + x Or, 1890 - 450 = x + 3x Or, 4x = 1440 Or, x = 360
