  • A. 18% p.a.
  • B. 22% p.a.
  • C. 20% p.a.
  • D. 24% p.a.
  • E. None of these.

Explanation: The third year's compound interest equals the second year's interest multiplied by 1 + r, because the second-year interest also earns…

Correct answer: 20% p.a.
  • A. Rs.4273
  • B. Rs.4613
  • C. Rs.4064
  • D. Rs.4266
  • E. None of these

Explanation: The two-year compound interest is Rs. 14,800 x [(1.135)^2 - 1] = Rs. 14,800 x 0.288225 = Rs. 4,265.73.

Correct answer: Rs.4266

  • C. Rs.18,028.80
  • D. Rs.17,828.80
  • E. None of these

Explanation: For two years at 8%, compound interest is P x [(1.08)^2 - 1] = P x 0.1664. Therefore P = Rs. 2,828.80/0.1664 = Rs.

Correct answer: Rs.19,828.80
  • A. Rs.460
  • B. Rs.5640
  • C. Rs.5460
  • D. Rs.5604

Explanation: The first year's balance is Rs. 5,000 x 1.04 = Rs. 5,200. Applying the second year's 5% rate gives Rs. 5,200 x 1.05 = Rs.

Correct answer: Rs.5460
  • A. 10
  • B. 11
  • C. 10.25
  • D. 10.15

Explanation: The total annual increase is 4% + 1% = 5%. Over 2 years, the population becomes 1.05 x 1.05 = 1.1025 of the original, so the percentage…

Correct answer: 10.25
  • A. Rs.150
  • B. Rs.140
  • C. Rs.130
  • D. Data insufficient for the answer

Explanation: The simple-interest amount gives P(1 + 2r) = Rs.1344, but both the principal P and rate r are unknown.

Correct answer: Data insufficient for the answer
  • A. Rs.2205
  • B. Rs.2200
  • C. Rs.2160
  • D. Rs.2040

Explanation: For quarterly compounding, the 20% annual rate becomes 20%/4 = 5% per quarter, and 6 months contains 2 quarters.

Correct answer: Rs.2205
  • A. Rs.482
  • B. Rs.424
  • C. Rs.842
  • D. Rs.512

Explanation: With half-yearly compounding, Amount = Rs.20000 x 1.10⁴ = Rs.29282, while yearly compounding gives Rs.20000 x 1.20² = Rs.28800.

Correct answer: Rs.482
  • A. 8500
  • B. 8000
  • C. 8100
  • D. 8400Downloading Interactive Party Trivia Games

Explanation: Let the initial population be P. After a 10% increase and then a 10% decrease, it becomes P x 1.10 x 0.90 = 0.99P, so 0.99P = 7920 and P =…

Correct answer: 8000
  • A. Rs.10
  • B. Rs.2
  • C. Rs.5
  • D. Rs.3

Explanation: For 2 years, the compound-interest excess over simple interest is P x r² = Rs.1250 x (0.04)² = Rs.1250 x 0.0016 = Rs.2.

Correct answer: Rs.2
  • A. Rs.635.50
  • B. Rs.613.50
  • C. Rs.675.50
  • D. Rs.653.50

Explanation: After 2 years, the debt is Rs.4000 x 1.05² = Rs.4410; after repaying Rs.2210, Rs.2200 remains.

Correct answer: Rs.635.50
  • A. Rs.81000
  • B. Rs.80000
  • C. Rs.75000
  • D. Rs.64000

Explanation: An increase by 1/8 means each year the amount is multiplied by 1 + 1/8 = 9/8.

Correct answer: Rs.81000
  • A. Rs.1261
  • B. Rs.9261
  • C. Rs.9621
  • D. Rs.9162

Correct answer: Rs.9261
  • A. Rs.8000
  • B. Rs.8400
  • C. Rs.7500
  • D. None

Explanation: The amount grows from Rs.8820 in year 2 to Rs.9261 in year 3, so the one-year growth factor is Rs.9261/Rs.8820 = 1.05, giving a 5% rate.

  • A. 1500
  • B. 1800
  • C. 2100
  • D. 1950

Explanation: For 2 years at 10% per annum, the compound-interest excess is P x (0.10)² = 0.01P. Hence Rs.15 = 0.01P, giving P = Rs.1500.

  • B. 1 year
  • C. 2 years
  • D. 4 years
