FV of each share = Rs 100
MV of each share = Rs 120
Number of shares purchased = 150
Sum invested = Number of shares purchased × MV of each share = 150 × 120 = Rs 18,000
Dividend received on each share = 7% of FV of each share = 7% of Rs 100 = × 100= Rs 7
Total dividend received = Number of shares purchased × Dividend received on each share = 150 × 7 = Rs 1,050
∴ Rate of return on investment = = 5.83%
Thus, the rate of return on investment is 5.83%.
