A sum of Rs.1550 was lent partly at 8% p.a. simple interest. The total interest received after 3 years was Rs.300. The ratio of the money lent at 5% to that lent at 8% is :
Choose the correct choice from the following options.
A) 16:18  B) 16:10  C) 16:15  D) 16:11  E) 16:12
let the sum lent at 5% be Rs.x and that lent at 8% be Rs.(1550-x). then,   Interest on x at 5% for 3 years + interest on (1550-x) at 8% for 3 years = 300   Required ratio = x : (1550-x) = 800 : (1550-800) = 800 : 750 = 16 : 15   Answer: 16:15) 16:15
