960.02 of 238.89 ÷ 144.01 of 79.97 = ?
- 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.)
320.98 + 49.99% of (261.09 + 138.98) = ?
? = 29.91% of 49.94% of ((56.25 × 4.09 + 23.01 × 7.89) × 99.98)
20.02% of (95.96 × 104.01 – 56.02 × 64.04) – ? = 12.02 × 39.96 + 103.03Â
