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

?% of (112 X 3 + 164) + 75 = 2 X 140 + 35

Find the simplified value of the given expression:

8 of 7 ÷ 2 × 5² + √36 – 10

(? + 180 + 13 × 6) ÷ 20 + 3.5 × 512 ^(1/3) = 8²

Find the simplified value of the following expression:

[{12 + (13 × 4 ÷ 2 ÷ 2) × 5 – 8} + 13 of 8]

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

? = (266 × 276) ÷ (114 × 161) × 17

Find the value of ‘y’ if (2/7) × y = 0.79 – 1.77 ÷ 3.

42 + 52% of 300 - ?% of 200 = 88

(12 × 8 + 7 ÷ 5) × 5 = ?
