89.87 × 3.21 + 60.32 = ? × (6.89 2 – 19.21)Â
What approximate value will replace the question mark (?) in the following?
√48...
66.05 × 17.95 – 38.99 × 18.12 = (60 + ?) × 6
999.99 + 99.99 + 99 = ?
( 22.01%  of 899.80 ) × 15.99 = ? 2 + 27.98 × 2400 ÷ 800
- 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 exact value.)
24.99% of 1619.78 + (1259.84 ÷ 12.24) = ? × 16.98
509.85 ÷ 15.05 + 210.16 – 18.06 × 5.95 = ?
12.052 + 36.15 × 25.45 – 124.15 × 15.05 = ? × 8.08 – 64.32 × 15.98
