464 + 181 +? = (154 × 25) - (15) ²  

Simplify the following expression:

    (525 +175) ² - (525 – 175) ² / (525 × 175)

25% of 250 + 32% of 200 = ? ÷ √ 16

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

Simplify the given expression.

(1/4) of {6 ⁴ - 28 × 15 + 13 × 16 - 12.5 of 12 ² }

13 X √? + 256 ÷ 4 = 30% of 900 - 50

? = (√784 - √361) + 10² - ³√512

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

√64 X 9 ÷ 3 + 12 X 3 = ? + 36
