Question

If $\frac{2}{5}$ of a numbers exceeds $\frac{2}{7}$ of the same number by $36$. Find the number .

Answer 1

Let required number is $=x$

Then according to the question,

$x\times \frac{2}{5}=x\times \frac{2}{7}+36$

$14x=10x+36\times 7\times 5$

$x=\frac{36\times 7\times 5}{4}=9\times 35=315$

$x=315$

Hence, this is the answer .
