A man invested Rs. 1552 in a stock at 97 to obtain an income of Rs. 128. The dividend from the stock is__________?
Correct answer: B. 8%
- A. 7.5%
- B. 8%
- C. 9.7%
- D. None of these
Explanation
At Rs. 97 per Rs. 100 stock, Rs. 1552 buys Rs. 1552 ÷ 97 x Rs. 100 = Rs. 1600 nominal stock. Since the income is Rs. 128, dividend rate = Rs. 128 ÷ Rs. 1600 x 100 = 8%. The likely trap is option c, 9.7%, which confuses the quotation of Rs. 97 with the dividend percentage.
