$7372 \times 7372 + 7372 \times 628 = ?$

$A$ number consists of two digits such that the digit in the ten's place is less by $2$ than the digit in the unit's place. Three times the number added to $\frac{6}{7}$ times the number obtained by reversing the digits equals $108$. The sum of the digits in the number is:

Thrice the square of a natural number decreased by $4$ times the number is equal to $50$ more than the number. The number is

$\frac{1}{16}$ of $8432 + 50 \%$ of $? = 4429$

$\frac{28 \times 36}{18 \% \text{ of } 50} = ?$

Two numbers are such that the ratio between them is $3:5;$ but if each is increased by $10,$ the ratio between them becomes $5:7.$ The numbers are
