Divide $36$ into two parts in such a way that the difference between $\frac{1}{5}$ of one part and $\frac{1}{7}$ of the other is equal to $0$.

Sam is $5$ years older to his sister. Four years later, he will be twice as old as his sister. Find their present ages

A number is divided into two parts such that one part is $33$ more than the other. Find the numbers, if the ratio between them is $3:4$

The length of the two equal sides of an isosceles triangle is $6 \mathrm{m}$ more than twice the length of the third side. If the perimeter of the triangle is $85 \mathrm{m}$, then find the dimensions of the triangle.

Three sides of a triangle measure $\left(2x+3\right)$ units, $\left(x+5\right)$ units, and $4x$ units. Find the measure of the sides, if its perimeter is $148$ units

In a fraction, the denominator is $1$ more than the numerator. If $1$ is subtracted from the numerator and $1$ is added to the denominator, the fraction becomes $\frac{1}{4}$. Find the number.

The length of a rectangle is $2$ more than its breadth. If the perimeter of the rectangle is $36 \mathrm{cm}$, then find the dimensions of the rectangle.

Five years from now, Sunil will be $1\frac{1}{2}$ times his present age. How old is he now?
