Profit he received =>
5,20,000 - 4,00,000 = Rs. 1,20,000
Given ratio of Investment in Mutual Funds to that of shares = 3:2
Take Investment in Mutual funds to be 3x and in shares to be 2x
Therefore Amount invested in Mutual Funds by Proportionality Theorem = 3x/(3x+2x) * 1,20,000
= 3/5 * 1,20,000
= Rs. 72,000
Therefore Amount invested in Shares = 1,20,000 - 72,000 = Rs.48,000
