The sum of $33 \%$ of a number and $14 \%$ of the same number is $3055$. What is $72 \%$ of that number?

The sum of two numbers is $25$ and their difference is $13$. Find their product.

$P, Q$ and $R$ scored $581$ runs such that $4$ times $P$'s runs are equal to $5$ times $Q$'s runs,which are equal to $7$ times $R$'s runs. Find the difference between $P$'s runs and $R$'s runs.

$1 \frac{5}{6} + 2 \frac{3}{5} + 4 \frac{2}{3} = ?$

$(21.98)^{2} - (25.02)^{2} + (13.03)^{2} = ?$

The difference between two positive integers is $3$. If the sum of their squares is $369$,then the sum of the numbers is
