If a mirror is placed on the line MN, then out of the

2/9 of 5/8 of 3/25 of ? = 40

600 ÷ 8 + 12 % of 250 + ? * 14 = 50 * √49

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

(44 × 72 ÷ 6) ÷ 11 = (9² + ?) ÷ 3

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

1020 ÷ 51 × 5 + 540 of 25% - 10 = ?² 

(6² - 5² ) % of 800 = 22 X √?

(?)² = {(26% of 35% of 3000) ÷ 3} × 91

What is 12% of 4% of 7% of 2 x 10⁶ ?

(2500 ÷ √625) × √(42.25) = ? ÷ 4

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