$24-[2.4-\{0.24 \times 2-(0.024-?)\}]=22.0584$

$(0.25)^{6} \div (0.125)^{2} \times (0.5)^{4} = (0.5)^{?+3}$

$(\sqrt{2209}-12) \times 5 = ?$

$9999 + 8888 + 777 + ? = 19700$

$A$ number when divided by $44$, gives $432$ as quotient and $0$ as remainder. What will be the remainder when dividing the same number by $31$?
