पर्याय

• ₹ 60,000

• ₹ 50,000

• ₹ 40,000

• ₹ 30,000

Answer 1

₹ 30,000

Explanation:

Let Avnish's income be ₹ A.

Then, Amount spent= 70% × A

= `70/100 xx A`

Remanung balance = `A - 70/100 xx A`

= `(30  A)/100`

Amount donated to orphanage = ₹ 1000

And Remaining balance = ₹ 8000

So, `(30  A)/100 - 1000` = 8000

⇒ `(30  A)/100` = 9000

⇒ A = `(9000 xx 100)/30` = 30000

Thus, his income is ₹ 30,000.
