Neco 2024 Commerce Question 47

An investor allocates ₦10,000 equally between two stocks A and B. Stock A is priced at ₦250 per share. Over three months its price changes: +8% month 1, -5% month 2, +6% month 3, and it pays a dividend of ₦4 per share at the end of month 3. Stock B is priced at ₦210 per share and is expected to grow at a constant monthly rate \\(r\\) (same each month) for three months, with no dividend. Using the allocated funds, the investor buys whole shares of each stock (any leftover cash is not used). What is the smallest integer percentage \\(r\\) (to the nearest whole percent) that makes the total return from Stock B at least equal to the total return from Stock A after three months?
