QUESTION:

If one seventh of a number is less than one fifth by 2 then the number is ______.

TO FIND:

The required number.

SOLUTION:

Let the required number be $x$.

BTP,

$\frac{1}{5}x - \frac{1}{7} x= 2 \\ => \frac{7x- 5x}{35} = 2 \\ => \frac{2x}{35} = 2 \\ => 2x = 2 \times 35 \\ => x = \frac{2 \times 35}{2} \\ => x = 35$

Hence, the required number is 35.
