If the sum of $4$ consecutive odd numbers is $184$,then find the largest number.

The smallest number between $400$ and $500$ which is divisible by $9$ is

$8000 \div 16 - 200 = ? \times 6$

Let $x$ be the smallest number,which when added to $2000$ makes the resulting number divisible by $12, 16, 18$ and $21$. The sum of the digits of $x$ is

Let $x$ be the least number,which when divided by $5, 6, 7$ and $8$ leaves a remainder $3$ in each case,but when divided by $9$ leaves no remainder. The sum of the digits of $x$ is:

$24$ is divided into two parts such that $7$ times the first part added to $5$ times the second part makes $146$. The first part is
