Here, FV = Rs. 100, MV = Rs.120
Dividend = 7%, Number of shares = 150
∴ Sum invested = Number of shares × MV
= 150 × 120
= Rs.18000
Dividend per share = 7% of FV
= (7/100) × 100 = Rs.7
∴ Total dividend of 150 shares
= 150 × 7 = Rs.1050
Now, return = (Total divident)/(Sum invested ) x 100
= (1050/18000) x 100 = 5.8/3%
∴ Rate of return on investment is 5.83%.
