Rs. 11,000 is divided between 8% stock at 80 and 9% stock at 108 so that the incomes from both are equal. How much goes into the 8% stock?
Correct answer C. Rs. 5,000
Explanation
Income per rupee is 8/80 = 1/10 and 9/108 = 1/12. Equal income needs investments in ratio 10 : 12 = 5 : 6, so 5/11 × 11,000 = Rs. 5,000.
