Question

the ratio of the expenditure to the saving of a family is 7:3. find the income of the expenditure is RS 6300.

Answer 1

Hi,

According to the problem given,

Ratio of expenditure and savings

= 7 : 3

Expenditure = Rs 6300

7 parts = 6300

1 part = 6300 / 7 = 900

Savings = 3 parts of the income

= 3 × 900

= Rs 2700

Total income = expenditure + savings

= Rs 6300 + Rs2700

= Rs 9000

Therefore,

Total income = Rs 9000

I hope this helps you.

Answer 2

we have total income
7x +3x=10x
given that expenditure= 6300=7x
so we have
7x = 6300
x=6300/7=900
we have total income=10x
x =900
10x=900*10
or 10x= 9000
so total income is 9000
