Answer 2

Answer:

$Monthly \: income = Rs\:21000$

Step-by-step explanation:

$Let \: monthly \: income \\of \:a \: person = Rs x$

$His \: monthly \: savings = Rs 3780$

According to the problem given,

$18\% \:of \: x = Rs\:3780$

$\implies 18\% \times \: x = Rs\:3780$

$\implies \frac{18}{100}\times x = 3780$

$\implies x = \frac{3780\times 100}{18}$

$\implies x = 210 \times 100$

$\implies x = Rs\:21000$

Therefore,

$Monthly \: income = Rs\:21000$
