60 = (? x 10 + 250)/5

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

? X 7 + (243)⁽²/⁵⁾ = 380 ÷ 2 + 71

The value of 15 × 14 – 30 + (3² + 17) is:

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

9 ^{(? + 12)} = 3 ^{(14 + 17 - 11)}

(√1296 – 12) × 5 = ? + 40

32% of 450 + 60% of 150 = ? × 9

390/? = √256 + 3.5

?% of (√196) × 24 + 344 = 428

22% of 280 + 34% of 1080 × 5/12 =? + 16% of 460
