The reciprocal of the sum of the reciprocals of $\frac{6}{5}$ and $\frac{3}{7}$ is:

The sum of three numbers is $2$. The $1^{\text{st}}$ number is $\frac{1}{2}$ times the $2^{\text{nd}}$ number and the $3^{\text{rd}}$ number is $\frac{1}{4}$ times the $2^{\text{nd}}$ number. The $2^{\text{nd}}$ number is

The product of three consecutive even numbers is $4032$. The product of the first and the third number is $252$. What is five times the second number?

$\sqrt[3]{1331} + \sqrt[3]{1728} = ?$

The least number which when divided by $6, 9, 12, 15, 18$ leaves the same remainder $2$ in each case is

$\frac{1}{4}$ of a number subtracted from $\frac{1}{3}$ of the same number gives $12$. The number is:
