The ratio of expenditure to the income of a person is 7 : 8. What amount will he save for month if his monthly salary is Rs. 64,000?
Let the expenditure and income be 7x and 8x respectively.
Monthly salary =Rs.64000(Given)
8x=64000
=640008=8000
Expenditure =7x=7×8000=56000
Therefore,
Saving = Income − Expenditure
Saving =64000−56000=Rs.8000
Hence the saving of the person Rs.8000.
