- 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.)
1219.98 ÷ 30.48 × 15.12 = ? × 2.16
24.99% of 1619.78 + (1259.84 ÷ 12.24) = ? × 16.98
(168.24 ÷ 23.98) x 19.81 + ? = 176.33
What approximate value should replace the question mark?
1 ÷ 9.08 of 242.60 + 40.10% of 200 = ?² - 61.92
390.11 ÷ 12.98 × 5.14 – 119.9 = √?Â
44.89% of 600.25 + (29.98 × 5.67) + (√1940 – 10.29) = ?2
(34.98% of 619.86 + 25.12% of 132.26) ÷ 14.86 × 23.98 = ? × 25.12
30.22% of (79.9 x 6.01) + 69.97 =?
