One of the following is not important in

What will come in the place of question mark (?) in the given expression? 

48 ÷ 4 × (3 + 5) – 6² + 10 = ?

4368 + 2158 – 596 - ? = 3421 + 1262

55 ÷ 11 × 6 + ?² = 47 × 2

240 + 25% of 420 – 145 =? + (2.5 + 8.5) ²

What will come in place of (?) in the given expression.

{(60% of 250) + √144} ÷ (3² - 4) = ?

436 × 794 – 68210 =? + 85730

1024 ÷ 16 + 800 ÷ √64 + ? = 200 * 2

Simplify the given expression.

What will come in the place of question mark (?) in the given expression?

(252 + 198) ÷ ? + 126 ÷ 3 = 144 ÷ 2

?% of 740 – 8% of 650 = 7.2
