If a mirror is placed on the line XY, then which of the

22 – 15 + 20 × 18 ÷ 6 – 34 = ?

311 × 17 = ? + 2482

12.5% of 45 % of 480 + 957/29 = ? -14 × 15

14 × 11 + 25 – ? = 21% of 300

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

? = ((180 × 27) ÷ 60) + ((52 × 70) ÷ (13 × 280))³ 

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

435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 3⁵ + 221 ÷ 17

(2 ÷ 3) × (4 ÷ 12) × (? ÷ 10) × 45 × (1 ÷ 5) = (? ÷ 6) + (2 ÷ 5)

Find the value of 325 × 5 + 31 × 21 – 22 × (63 − 52).
