Answer 2

Answer:

Income is Rs.6480

Step-by-step explanation:

Given : The ratio of the income to the expenditure of a family is 9:4.

To find : The income if saving is ₹3600?

Solution :

Let income be x ,

The ratio of the income to the expenditure of a family is 9:4.

So, Income = 9x

Expenditure = 4x

Savings = Income-Expenditure

$3600= 9x - 4x\\3600= 5x\\x=\frac{3600}{5}\\x= 720$

Then,

Income = $9\times720=Rs.6480$

Expenditure =$4\times720=Rs.2880$
