124.88% of 60.101 + 18.09% of 849.87 – 22.12% of 1049.93= ? – 19.93

6.99² + (2.01 × 2.98) + ? = 175.03

45.22% of (71.9 x 5.01) + 69.97 =? 

Find the approximate value of Question mark(?) for given equation. 

(47.98 × 34.85 ÷ 7.09) – (80.81 ÷ 9.02 × 5.01) = ?

√28561.11  ×  √ 960.9  – (18.02)²  =? × 4.95 

? = 22.08 + 13.99 × 22.07

? + 96.18 – 15.02 = 118.98 + 31.09

12, 16, ?, 36, 52, 72 

What approximate value should come in the place of (?) in the following questions?

19.98% of 349.89- √290 * ? = √82 % of 399

√784 × 3 + (713.99 ÷ 6.98) = ?% of 619.99
