Ratio of profit shares of Billu and Bhaga after 1 year: = {(x + 2400) X 4 + (x + 2400) X 0.5 X 8}:(2x X 12) = {(4x + 9600) + (4x + 9600) }:24x = (8x + 19,200) :24x = (x + 2400) :3x So, profit share of 'B' = 48000 - 24000 = Rs. 24,000 ATQ; {(x + 2400) /3x} = (24000/24000) Or, x + 2400 = 3x Or, 2400 = 2x So, 'x' = 1200 So, investment of Billu = 1200 + 2400 = Rs. 3,600
