Find the yield on a 5% stock of Rs. 100 bought at a discount of Rs. 20.
Answer:
6.25%
Face Value = Rs. 100. Discount = Rs. 20, so Market Value = 100 - 20 = Rs. 80. Dividend = 5% of 100 = Rs. 5. Yield = (5 / 80) × 100 = 6.25%.

Answer:
8.75%
Dividend per share = 14% of 100 = Rs. 14. Market Value = Rs. 160. Rate of return = (14 / 160) × 100 = 8.75%.

A man invests Rs. 4,000 in an 8% stock of Rs. 100 at Rs. 80. Find his rate of return.
Answer:
10%
The rate of return is independent of the total investment amount. Rate of return = (Dividend per share / Market Value) × 100. Dividend = 8% of 100 = Rs. 8. Yield = (8 / 80) × 100 = 10%.
167
What is the rate of return on a 10% stock of Rs. 10 bought at Rs. 8?
