Find the wrong number in the given number series.

(?)² = {(26% of 35% of 3000) ÷ 3} × 91

Simplify the following expressions and choose the correct option.

40% of 360 + 25% of 248 - 30

Evaluate

32 ÷ 2 of 7 of [14 ÷ 7 of (6 ÷ 3 + 5)] + (6 ÷ 2 + 1)

√324 + √576 = ?/ √9

[1.45 X 1.45 X 1.45 + 0.55 X 0.55 X 0.55 + 4.785] = ?

40% of 50 + 50% of ? = 25% of 300 - 10% of 250

`sqrt(7744)`   - `sqrt(4761)` + `sqrt(8281)`  + `sqrt(5625)` + ? = 1856 

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

(11/45) of 225 + 3 X 75 = ? X (72 ÷ 6 + 4)

Find the simplified value of the given expression.
