Answer 2

Answer:

The ratio of monthly income to the savings in a family 7 : 3. If the savings be rs 15000, then the expenses ​is Rs. 20000.

Step-by-step explanation:

If the common multiple is x

Then monthly income = 7x

and savings = 3x

If the savings be rs 15000

means 3x = 15000

x = 15000/3

x =  Rs 5000

So, monthly income = 7x = 7(5000) = 35000

The expenses = monthly income - savings

= 35000 - 15000

= 20000 Rs

Hence the monthly expenses is Rs. 20000.
