ratio \: of \: initial\: investments = 7/2 : 4/3 : 6/5 = 105 : 40 : 36

Let\: the\: initial \: investments \: be\: Rs 105x,\: 40x\: and\: 36x

So, \: A:B:C= \left [ \left ( 105x\ast 4 \right ) + \left ( 150/100 \right )\ast 105x\ast 8 \right ] : (40x\ast 12) : (36x\ast 12)

                              = 1680x : 480x : 432x

                               = 35 : 10 : 9

Hence\: B's \: share = Rs \left ( 21600\ast 10/54 \right ) = Rs. 4000
