  • A. Rs. 3096
  • B. Rs. 4076
  • C. Rs. 4085
  • D. Rs. 4096Education

Explanation: The amount factor for 6.25% compound interest over 3 years is (1.0625)^3 = (17/16)^3 = 4913/4096. Thus the principal is Rs.

Correct answer: Rs. 4096Education
  • A. 2
  • B. 2 1/2
  • C. 3
  • D. 4

Explanation: For 2 years, the compound interest on Rs. 30,000 at 7% is Rs. 30,000[(1.07)^2 - 1] = Rs. 30,000 x 0.1449 = Rs. 4347.

Correct answer: 2
  • A. Rs. 2.50
  • B. Rs. 3
  • C. Rs. 3.75
  • D. Rs. 4

Explanation: With half-yearly compounding, the rate per half-year is 5% and there are 2 periods in 1 year. Compound interest is Rs.

Correct answer: Rs. 3
  • A. Rs. 31
  • B. Rs. 32.10
  • C. Rs. 40.40
  • D. Rs. 64.10

Explanation: Compound interest after 4 years is Rs. 1000[(1.10)^4 - 1] = Rs. 464.10, whereas simple interest is Rs. 1000 x 10 x 4 / 100 = Rs. 400.

Correct answer: Rs. 64.10
  • A. Rs. 51.25
  • B. Rs. 52
  • C. Rs. 54.25
  • D. Rs. 60

Explanation: From simple interest, Rs. 50 = P x 5 x 2 / 100, so the principal is P = Rs. 500. Compound interest for 2 years is Rs.

Correct answer: Rs. 51.25
  • A. Rs. 1851
  • B. Rs. 1941
  • C. Rs. 1951
  • D. Rs. 1961

Explanation: Nine months contains 3 quarterly periods, and the quarterly rate is 16% / 4 = 4%. Compound interest is Rs. 15,625[(1.04)^3 - 1] = Rs.
