20.05% of 150.05 – 12.15% of 99.99 × 2.02 = ?
(6.93)2 × (11.98)2 ÷ √361.2 = 7?Â
89.87 × 3.21 + 60.32 = ? × (6.89 2 – 19.21)Â
Find the approximate value of Question mark(?). No need to find the exact value.
59.88% of 419.78 + (24.09 × 5) ÷ 3 – √(80.81) = ?
...7.9% of 174.92 + 24.99 - 131.99 ÷ 11.95 × 2.98 = ?
? 3 + 95.06 X 39.87 ÷ 5.03 = 1271.89
49.99% of 639.99 + 159.98% of 49.99 = ?2
- 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.)
1299.99 ÷ 20.21 = ? + 325.985 - (180 ÷ 6 × 24.03)
1519.98 ÷ 50.48 × 15.12 = ? × 4.16
