Question

Find the whole amount whose 5% is Rs 40

Answer 1

Question :-

5% of an amount is ₹ 40. Find the amount.

Now,

Let the unknown amount be '$x$'

Thus,

5% of $x$ is ₹ 40.

$\frac{5x}{100} =40$

$=>5x=40$ × $100$

$=>5x=4000$

$=>x=4000\div5$

$=>x=800$

Verification :-

$LHS=5$% $of$ $x$

$=\frac{5}{100}$ × $800$

$=5$ × $8$

$=40$

$RHS=40$

$LHS=RHS$ $hence,$ $verified.$

Thus,

$The$ $value$ $of$ $the$ $unknown$ $amount$ $is$ ₹ $800.$
