Simplify the expression: 45 - [38 - (60 / 3 - 6 - 9)].
Correct Option
Explanation
Inner bracket first: (20 - 6 - 9) = 5. Outer bracket: [38 - 5] = 33. Finally: 45 - 33 = 12.
82
Evaluate: 25 * 3 - 45 / 9 + 12.
Correct Option
Explanation
Follow BODMAS: Division (45/9 = 5), Multiplication (25*3 = 75). Equation: 75 - 5 + 12 = 70 + 12 = 82.
83
Find the value of: 14 + 6 * 2 / 3 - 5.
Correct Option
Explanation
Division/Multiplication left-to-right: 6 * 2 = 12, then 12 / 3 = 4. Equation: 14 + 4 - 5 = 18 - 5 = 13.
84
Simplify: 108 / 36 * 4 + 2.5 * 4.
Correct Option
Explanation
Division and Multiplication: 108 / 36 = 3, then 3 * 4 = 12. And 2.5 * 4 = 10. Equation: 12 + 10 = 22.
85
Evaluate: 18 * 4 + 15 / 5 - 20.
Correct Option
Explanation
Multiplication and Division: 18 * 4 = 72, and 15 / 5 = 3. Equation: 72 + 3 - 20 = 75 - 20 = 55.
86
Find the value of: 3/4 of 24 + 5/6 of 30.
Correct Option
Explanation
Calculate 'of' logic: 3/4 * 24 = 18. And 5/6 * 30 = 25. Addition: 18 + 25 = 43.
87
Simplify: 1.2 * 0.5 + 3.6 / 0.9.
Correct Option
Explanation
Multiplication and Division: 1.2 * 0.5 = 0.6, and 3.6 / 0.9 = 4. Equation: 0.6 + 4 = 4.6.
88
Evaluate: (15 + 5) * (18 / 6) - 10.
Correct Option
Explanation
Brackets first: (15 + 5) = 20 and (18 / 6) = 3. Equation: 20 * 3 - 10 = 60 - 10 = 50.
89
Find the value of: 10% of 500 + 15% of 200.
Correct Option
Explanation
Calculate percentages: 10% of 500 = 50. And 15% of 200 = 30. Addition: 50 + 30 = 80.
90
Simplify: 4^3 - 2^5 + sqrt(144).
Correct Option
Explanation
Solve powers and roots: 4^3 = 64, 2^5 = 32, and sqrt(144) = 12. Equation: 64 - 32 + 12 = 32 + 12 = 44.
91
What approximate value should come in place of x: 39.99% of 400.02 + 19.98 = x.
Correct Option
Explanation
Approximate to 40% of 400 + 20. Percentage: (40/100)*400 = 160. Addition: 160 + 20 = 180.
92
Find the approximate value: 12.01^2 - 14.99 * 4.01.
Correct Option
Explanation
Approximate to 12^2 - 15 * 4. Evaluate: 144 - 60 = 84.
93
Approximate the value of: sqrt(1023.95) * 5.01 + 10.05.
Correct Option
Explanation
Approximate to sqrt(1024) * 5 + 10. Square root of 1024 is 32. Evaluate: 32 * 5 + 10 = 160 + 10 = 170.
94
What approximate value should come in place of the question mark: 59.98% of 250.05 - 24.99% of 119.98 = ?
Correct Option
Explanation
Approximate to 60% of 250 - 25% of 120. Percentages: 150 - 30 = 120.
95
Find the approximate value: 499.98 / 24.95 + 15.01 * 3.99.
Correct Option
Explanation
Approximate to 500 / 25 + 15 * 4. Follow BODMAS: 20 + 60 = 80.
96
Approximate: sqrt(255.95) / 3.99 * 5.05.
Correct Option
Explanation
Approximate to sqrt(256) / 4 * 5. Evaluate: 16 / 4 * 5 = 4 * 5 = 20.
97
