* THE RATIO OF INCOMETO SAVINGSOF A FAMILY IS 11;2. FIND THE EXPENDITURE IF THE SAVING IS Rs. 1520 *

Total income = expenditure + saving

So let the income be 11

*x*, then the saving will be 2

*x*

And the saving is given as Rs 1520

So 2

*x*= Rs1520

or

*x*= Rs 760

So the income will be 11

*x*=11тип760 = Rs 8360

As Rs 8360 = expenditure + Rs1520

So expenditure = Rs 8360 - Rs1520 = Rs 6840

Hence the expenditure of the family is Rs 6840
