The amount at the end of the 2nd and 3rd years on a certain principal at CI is ₹9,680 and ₹10,648 respectively. Find the principal.
Answer
The correct answer is B: ₹8,000. Rate = (10648 − 9680)/9680 × 100 = 968/9680 × 100 = 10%. Amount after 2 years = P(1.1)² = 9680, so P = 9680/1.21 = ₹8,000.
- A.₹7,000
- B.₹8,000✓ Correct
- C.₹8,800
- D.₹9,000
Rate = (10648 − 9680)/9680 × 100 = 968/9680 × 100 = 10%. Amount after 2 years = P(1.1)² = 9680, so P = 9680/1.21 = ₹8,000.
