Answer 2

Given,

A man named, Avnish spends 70% of his income.

From his balance account, he also donates Rs. 1000 to an orphanage to help him/her.

After all of those he can have only rupees 8.

To Find,

The income of Avnish.

Solution,

At first, suppose that the income of Avinash is a.

Given that, he spends a total of 70% of his income.

So he spends, a×$\frac{70}{100}$ = $\frac{7a}{10}$ rupees

He also donates Rs. 1000 to an orphanage.

After that money left is = (Total income - money spend)=(a- $\frac{7a}{10}$-1000).

Given total money left is 8 rupees only.

Hence,

(a- $\frac{7a}{10}$-1000)=8.

⇒$\frac{10a-7a}{10}$=8+1000.

⇒$\frac{3a}{10} =1008.$

⇒a=$\frac{10080}{3}$.

⇒a=3360.

Hence,  his income is rupees 3360.
