Q60
ArithmeticSimple & Compound Interest
If the sum of ₹ 500 amounts to ₹ 575 in 3 years, how much will ₹ 600 to in 4 years at the same rate of simple interest?
  1. a.₹ 120
  2. b.₹ 620
  3. c.₹ 650
  4. d.₹ 720

Answer: (D) ₹ 720

Interest of ₹ 75 on ₹ 500 in 3 years means a rate of 75 ÷ (500 × 3) × 100 = 5%. On ₹ 600 for 4 years the interest is ₹ 120, so the amount is ₹ 720. ₹ 120 is only the interest, not the amount.
