​

Answer 1

Answer:

Mr.Raj's total income is $Rs\ 15000$.

Step-by-step explanation:

Let the income of Mr.Raj $=x$, on which he spent $20\%$ on house rent.

That is house rent $=x*\frac{20}{100} =\frac{20x}{100}$,

remaining income $=\frac{80x}{100}$, out of which he spends $70\%$ on house hold expenditure.

So he saves the remaining $30\%$.

That is he saves $\frac{80x}{100}*\frac{30}{100} =3600$

                           $x=3600*(\frac{10000}{2400})\\\\x=15000$.

So his total income is Rs $15000$

Hence the answer
