- B. 4%
- C. 5%
- D. 6 2/3 %
Explanation: From the third to the fourth year, the amount rises from Rs.800 to Rs.840, so one year's interest is Rs.840 - Rs.800 = Rs.40.
Correct answer: 5%- A. 10%
- B. 10.5%
- C. 12%
- D. None of these
Explanation: The difference is Rs.696.30 - Rs.660 = Rs.36. For 2 years, the difference divided by the simple interest equals r/2, so r = 2 x Rs.36 ÷…
Correct answer: None of these- A. 625
- B. 630
- C. 640
- D. 650
Explanation: For 2 years at 4% per annum, the difference is P x (4/100)^2 = P x 0.0016.
Correct answer: 625- A. Rs. 2160
- B. Rs. 3120
- C. Rs. 3972
- D. Rs. 6240
Explanation: A 60% simple-interest increase in 6 years means the annual rate is 60% ÷ 6 = 10% per annum.
Correct answer: Rs. 3972- A. 1350
- B. 1450
- C. 1550
- D. 1421
Explanation: Since 3√196 = 3 x 14 = 42, the equation becomes (50 - ?/29)% of 4200 = 42.
Correct answer: 1421- A. 1500
- B. 1750
- C. 9000
- D. 7500
Explanation: The increase from 9000 to 10500 is 1500. Since 16 2/3% equals 1/6, the required number satisfies ?/6 = 1500, so ? = 1500 x 6 = 9000.
Correct answer: 9000- A. 2500
- B. 3500
- C. 3600
- D. 4500
Explanation: Find each percentage: 26.98% of 6002 = 0.2698 x 6002 = 1619.34, and 45.01% of 4199 = 0.4501 x 4199 = 1889.97.
Correct answer: 3500- A. 167
- B. 154
- C. 162
- D. 181
Explanation: Convert 332% to 3.32: 3.32 x 2113 = 7015.16. Dividing by 42 gives 7015.16 / 42 = 167.03, approximately 167, option a.
Correct answer: 167- A. 140
- B. 120
- C. 160
- D. 180
Explanation: Twenty percent of 40 is (20/100) x 40 = 8, leaving 120 - 8 = 112 for the second term.
Correct answer: 140- A. 20
- B. 40
- C. 60
- D. 80
Explanation: Calculate 32% of 425: 0.32 × 425 = 136. Hence 136 - (x/100 × 250) = 36, so x/100 × 250 = 100 and x = 40%.
Correct answer: 40- A. 312.73
- B. 373.12
- C. 337.12
- D. 339.12
Explanation: Convert 43% to 0.43 and multiply: 0.43 × 784 = 337.12. Therefore option c is correct.
Correct answer: 337.12- A. 4
- B. 0.1
- C. 1
- D. 0.4Downloading Interactive Party Trivia Games
Explanation: Forty percent of 160 is 0.40 x 160 = 64, while 17% of 400 is 0.17 x 400 = 68. Therefore ?% of 400 = 68 - 64 = 4, so ?
Correct answer: 1- A. 7
- B. 10
- C. 15
- D. 49
Explanation: Using 33.33% as the intended approximation to 1/3, (27 + 3) ÷ 5 = 6 and 1/3 of 6 = 2.
Correct answer: 7- A. 25
- B. 125
- C. 241/5
- D. 253/5
Explanation: Inside the percentage term, 26/13 + 24/12 + 21 = 2 + 2 + 21 = 25, and 60% of 25 = 15.
Correct answer: 25- A. 90
- B. 270
- C. 810
- D. 240
Explanation: The intended values are 16.66% = 1/6, 33.33% = 1/3, and 66.66% = 2/3. Their product is 1/6 x 1/3 x 2/3 = 1/27, so ? ÷ 27 = 30 and ?

- B. x = 20, y = 40
- C. x = 20, y = 80
- D. Cannot be determined
Explanation: x% of 80 is 80x/100 = 0.8x, while 20% of y is 20y/100 = 0.2y. Thus 0.8x = 0.2y, giving y = 4x, so many pairs are possible and the exact…
Correct answer: Cannot be determined- A. Neither increased nor decreased
- B. Increased by 1%
- C. Decreased by 1%
- D. Decreased by 10%
Explanation: Let the original area be L × B. After the changes, the new area is 110% of L × 90% of B, so it is 1.10 × 0.90 = 0.99 times the original…
Correct answer: Decreased by 1%- A. 1.01%
- B. 5.01%
- C. 3.01%
- D. 2.01%
Explanation: If the original radius is r, the new radius is 1.01r. Since area is proportional to the square of the radius, the new area is (1.01)²A =…
Correct answer: 2.01%- A. 52.65
- B. 56.25
- C. 50.75
- D. 42.75
Explanation: Let the original side be s, so the new side is 1.25s. The new area is (1.25s)² = 1.5625s², which is 56.25% greater than s².
Correct answer: 56.25
