Rs. 12,000 is lent partly at 8% and partly at 13% simple interest per annum. If the total interest after one year is Rs. 1,110, how much was lent at 13%?
Correct answer A. Rs. 3000
Explanation
Average rate = 1110/12000 x 100 = 9.25%. Ratio 8% : 13% = (13 - 9.25) : (9.25 - 8) = 3 : 1, so Rs. 3000 at 13%.
