Find the number whose four-fifth is more than its

33 × 5 - ?% of 250 = 6² - 6

360 × 9 ÷ 3 + 120 + 900 ÷ 5 = ?

Simplify the following expression:

(16⁴-1)/17×15× (2⁸+1)

3% of 842 ÷ 2% of 421 = ?

((67)³² × (67)^-18 / ? = (67)⁸

2(3/4) of 2880 + 54% of 7520 - ? = 30²

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

{(16 × 25) ÷ 32} × 12 = ? – 200

? = 120% of (65² ÷ 13² ) + 33 × 8

Find the simplified value of the given expression.

{12.75 × √64 + 13.5 × √(√256)} ÷ 6 + 49.5 ÷ 5.5 

24% of 400 × 16% of ? = 384
