Kavya invested amounts in three schemes P, Q, and R at simple interest rates of 11% p.a., 13% p.a., and 16% p.a. respectively. If the total interest in one year was ₹2,850 and the amount in Scheme R was 200% of Scheme P and 300% of Scheme Q, what was the amount invested in Scheme Q?
- ₹ 3677
- ₹ 2750
- ₹ 3000
- ₹ 3250
Correct answer: ₹ 3677
Solution
Let the investment in P be x, in Q be y, and in R be 2x. Also, R is 300% of Q, so 2x = 3y, hence x = 1.5y. Total interest for one year is 11% of x + 13% of y + 16% of 2x = 2850. Solving gives y = 3676.92, which rounds to ₹3677.
