The least prime number is

How many numbers up to $500$ are divisible by $23$?

$250 \%$ of $? \div 250 - 444 = 200$

If a six-digit number $53a29b$ is divisible by $88$,then find the value of $a$ and $b$.

If doubling a number and adding $20$ to the result gives the same answer as multiplying the number by $8$ and taking away $4$ from the product,the number is

$\sqrt{?} \%$ of $160 = 128 \div 4$
