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 11x, then the saving will be 2x
And the saving is given as Rs 1520
So 2x = Rs1520
or x = Rs 760
So the income will be 11x =11⨯760 = Rs 8360
As Rs 8360 = expenditure + Rs1520
So expenditure = Rs 8360 - Rs1520 = Rs 6840
Hence the expenditure of the family is Rs 6840
Ratio of income to savings =11:2
So, out of the total 13 parts, 2 parts are of savings and other 11 parts of income so when we will divide Rs.1520 that is the savings by 2 we will get 1 part of the 13 parts.
So, when we will multiply 1 part by 11 we will get the expenditure.
760 multiplied by 11 = 8360
So, Rs. 8360 is the expenditure and the income is 8360 + 1520=9880
