(1800.23 ÷ 29.98) + (816.32 ÷ 23.9) + 1634.11 = ?
20.11% of 159.99 + √99.97 ÷ 5.02 = ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
35.05% of 14.87 × (13.02 – ?) + 30.19 = 188.7
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
35.05% of 200.05 – 20.15% of 99.99 × 3.02 = ?
31.98% of 224.99 = 24.98% of ? + 9.91% of 499.99Â
837.04 × 4.02 + 40.04% of 3049.98 – 3667.82 = ? 2 – 60.87
(3/7 of 1049.88 + 44.95% of 799.79) ÷ (√168.89 + 24.77% of 400.11) = ?
