25% of 250 + 32% of 200 = ? ÷ √ 16
(2/?) x (3/16) x (2/15) x 60 = 1/3
- Find the simplified value of the given expression.

Determine the value of 'p' in the expression.
28 ÷ 22p + 1 = 43
((67)32 × (67)-18 / ? = (67)⁸
[1.45 X 1.45 X 1.45 + 0.55 X 0.55 X 0.55 + 4.785] = ?
What will come in the place of question mark (?) in the given expression?
(144 × 16 ÷ 12) × 6 = ?
16 × ? + 36% of 250 = 410
192.251 + 326.233 + 125.021 + 19.273 = ?
4387897 – 3286871 – 51926 = ?
