(804/65) ÷ (11/798) × (129/131) =

Simplify the following expression:

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

25% of 1280 + (41 × 4) = ?² 

If 960 ÷ 16 + 875 ÷ 25 - x + 28 × 6 = 1350 ÷ 18 × 222 ÷ 37, then the value of x is:

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

? = (266 × 276) ÷ (114 × 161) × 17

(165 × 12) ÷ 45 + 110 = ? × 2

535 + ? × 27 - 22 × 20 = 230 

? = 2640 ÷ {(35% of 1240) – 170} 

375% of 320 - 80% of 40 ÷ √256 = ?

? = 6.25% of 240 + 25 ² + 17 ² – 16 × 17

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

(√1089 + 84 ÷ 2) % of 348 = 416 - ?
