Divide Rs. 760among A, B, C such that A gets 5/6 of what B gets and the ratio between the shares of B and C is 3:4

Let amount of B = x then amount of A = 5x/6 and ratio of B/C=3/4 so, x/C = 3/4 therefore amount of C = 4x/3 A/Q, A+B+C = 760

or 5x/6 + x +4x/3 = 760

or 19x/6 = 760

or x = 760*6/19 = 240

therefore amounts of A = 5*240/6 = 200 rupees B = 240 rupees C = 320 rupees
