If A denotes ‘+’, B denotes ‘×’, C denotes

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

[192 ÷ 6 × 5] ÷ (? + 3) = 20 

18(1/3) + 9(2/3) – 10(1/3) = 1(2/3) + ?

(〖(0.4)〗^(1/3)  × 〖(1/64)〗^(1/4)  × 〖16〗^(1/6)  × 〖(0.256)〗^(2/3))/(〖(0.16)〗^(2/3)  × 4^(-1/2)  ×〖1024〗^(-1/4) ) = ?

(13 X 11) + (19 X 3) = 400% of √?

(6² - 5² ) % of 800 = 22 X √?

What will be the value of the following expression?

0.04 ÷0.002 × 0.05 × 50

4^? + 8² = 22% of 300

(506 ÷ 22 + 9 × 3) × ? = 900 ÷ 9

√ 729 × 5 – 220 % of 15 + ? = 120% of 160
