'A', 'B' and 'C' distributed Rs. 720 among themselves in
the ratio 4:3:2, 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' = 720 × (4/9) = Rs. 320 Amount received by 'B' = 720 × (3/9) = Rs. 240 Let Amount given by 'A' to 'B' be Rs. 'x' According to the question, 3 × (320 - x) = 240 + x Or, 960 - 3x = 240 + x Or, 960 - 240 = x + 3x Or, 720 = 4x Or, x = 180
