What approximate value should come in place of x: 39.99% of 400.02 + 19.98 = x.
Option C
Approximate to 40% of 400 + 20. Percentage: (40/100)*400 = 160. Addition: 160 + 20 = 180.

Approximate to 40% of 400 + 20. Percentage: (40/100)*400 = 160. Addition: 160 + 20 = 180.
Solve powers and roots: 4^3 = 64, 2^5 = 32, and sqrt(144) = 12. Equation: 64 - 32 + 12 = 32 + 12 = 44.
Calculate percentages: 10% of 500 = 50. And 15% of 200 = 30. Addition: 50 + 30 = 80.
Brackets first: (15 + 5) = 20 and (18 / 6) = 3. Equation: 20 * 3 - 10 = 60 - 10 = 50.
Multiplication and Division: 1.2 * 0.5 = 0.6, and 3.6 / 0.9 = 4. Equation: 0.6 + 4 = 4.6.
Calculate 'of' logic: 3/4 * 24 = 18. And 5/6 * 30 = 25. Addition: 18 + 25 = 43.
Multiplication and Division: 18 * 4 = 72, and 15 / 5 = 3. Equation: 72 + 3 - 20 = 75 - 20 = 55.
Division and Multiplication: 108 / 36 = 3, then 3 * 4 = 12. And 2.5 * 4 = 10. Equation: 12 + 10 = 22.
Division/Multiplication left-to-right: 6 * 2 = 12, then 12 / 3 = 4. Equation: 14 + 4 - 5 = 18 - 5 = 13.
Follow BODMAS: Division (45/9 = 5), Multiplication (25*3 = 75). Equation: 75 - 5 + 12 = 70 + 12 = 82.
