For the next two (02) items that follow:
A person borrows a sum of ₹16,000 on simple interest at the beginning of a year. After 4 months, ₹24,000 more is borrowed on a rate of interest double the previous one. At the end of the year, the total interest on both the loans is ₹4800.
90. What is the ratio of the interest on the first loan to the interest on the second loan?
Elementary MathematicsSimple and Compound Interest
- A1 : 2
- B2 : 3
- C3 : 4
- D4 : 5
Explanation
Interest on the first loan is 16000×0.10=1600 and on the second 24000×0.20×(8/12)=3200, a ratio of 1:2, option A. The ratio is independent of the rate r, since both interests scale with it. Computing only one loan's interest is the typical error.
