Question

The ratio of the expenditure to the savings of a family is7:3. Find the income if the expenditure is Rs.6300

Answer 1

Ratio of expenditure and savings = 7 : 3


Expenditure = Rs. 6300


7 parts = 6300

1 part = $\frac{6300}{7}$

= 900


Savings = 3 parts of the income

3 × 900

= 2700


Total income = expenditure + savings

= Rs. 6300 + Rs. 2700

= Rs. 9000


Total income = Rs. 9000

Answer 2

let expenditure be 7x
saving be 3x
expenditure equal to 6300(given)
7x=6300
x=900
saving 3*900=2700
income= 6300+2700=9000
