54.8% of 800 - √(?) = 33.98% of 400 – 12.42% of 300
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.)<...
³√? `xx` 32.87 + 59.83 `xx` 28.7665 – 48.8745 `xx` 21.642 = 1085.344
{(1799.89 ÷ 8.18) ÷ 9.09 + 175.15} = 25.05% of ?
124% of 620.99 + 11.65% of 1279.23 = ?
3.98 × 29.67 ÷ 11.90 of √24.89 = ?% of 199.79
11.06 2 – 7.12 × 4.88 + 9.96 = 12.22 × ?Â
( 14.99%  of 549.99 ) × 17.02 = ? 2 + 26.02 × 3200 ÷ 800
What approximate value will come in place of question (?) in the following given expression? You are not expected to calculate the exact value.
...? * 8.21 = (520.12 ÷ 12.98) % of 6800 - 1350.75
