(?)2 + 3.113 = 22.92 – 61.03
What approximate value should come in place of question mark (?) in the following equations?
39.9% of 1720 + 80.2% of 630 = 89.9% of 1280 + ?
√2023.85 + (24.77% of 1999.73) - (3/8 of 799.91) = ?
(5.89 × 4.76) + (3.65 × 14.89) = ? × 5.76
√483.98 + 120.02 of 119.89 ÷ 59.87 of 29.87 = ?
2660.03 ÷ 94.98 x 59.9 = ? + 20.32
1 ÷ 6.43 of 191.90+75.03% of 220=?²-202.9
{(23.65 × 35.12) ÷ 6.97} + 179.86 = ? × 14.76
(√360.99 + 161.14) ÷ 5× 249.98 = ?
? + 163.99 – 108.01 = 25.01 × 6.98
