Concept: The question tests on the basics of Counting
Solution:
Ratio of which profits are shared depends on the investments made and the time period for which they they are made.
In effect Pa : Pb : Pc = Ia x ta : Ib x tb : Ic x tc, where t is in months.
Is = 160000, ts = 12 months, Ir = 240000, tr = 3 months, Ik = 200000 and tk = 6 months
Therefore Ps : Pr : Pk = (160000 * 12) : (240000 * 3) : (200000 * 6) = 8 : 3 : 5
Sohan's share = 816∗120000=$60,000816∗120000=$60,000
