Find the approximate value: 19.98% of 400.05.
Correct Option
Explanation
Approximate to 20% of 400. 20% is 1/5, so (1/5) * 400 = 80.
62
Approximate: 24.95% of 120.01.
Correct Option
Explanation
Approximate to 25% of 120. 25% is 1/4, so 120 / 4 = 30.
63
What approximate value should come in place of the question mark: 33.33% of 89.98 = ?
Correct Option
Explanation
Approximate to 33.33% (or 1/3) of 90. Calculation: (1/3) * 90 = 30.
64
Approximate the value: 50.01% of 240.05.
Correct Option
Explanation
Approximate to 50% of 240. 50% is half, so 240 / 2 = 120.
65
Find the approximate value: 9.99% of 499.95 + 10.01.
Correct Option
Explanation
Approximate to 10% of 500 + 10. First calculate percentage: 50. Then add 10: 50 + 10 = 60.
66
Approximate: 74.95% of 159.98.
Correct Option
Explanation
Approximate to 75% of 160. 75% is 3/4, so (3/4) * 160 = 120.
67
What approximate value will come in place of x: 40.05% of 299.95 - 20.01 = x.
Correct Option
Explanation
Approximate to 40% of 300 - 20. 40% of 300 is 120. Subtraction: 120 - 20 = 100.
68
Find the approximate value: 12.48% of 800.02.
Correct Option
Explanation
Approximate to 12.5% of 800. 12.5% is 1/8, so (1/8) * 800 = 100.
69

Correct Option
Explanation
Approximate to 60% of 150. Calculation: (60/100) * 150 = 90.
70
What approximate value should come in place of the question mark: 79.99% of 50.01 = ?
Correct Option
Explanation
Approximate to 80% of 50. Calculation: (80/100) * 50 = 40.
71
