- 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.)
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exactvalue.)
(1680.23 ÷ 27.98) + (600.32 ÷ 23.9) + 1384.11 = ?
What approximate value should replace the question mark?
27.48% of 600.06 + ?% of 200.01 = 284.94
(44.79 × 74.21) ÷ (11.862 – 33.12) + 37.48% of ? = 180.23
2090.03 ÷ 54.98 x 49.9 = ? + 20.32
√92.10 + √256.30 + 60.78% of (420.90 + 19.36% of 140.25) = ?
(22.03 + 89.98) ÷ 14.211 = 89.9 – 25.23% of ?
