Question

The ratio of the expenditure to the saving of a family is 7:3 find the income if the expenditure is 6300

Answer 1

e:s=7:3
let e=7x and s=3x
so 7x=6300
x=6300/7=900
expenditure=900
savings=3×900=2700
income=expenditure+savings
=6300+2700=9000

Answer 2

$\large{\boxed{\bold{Solution:}}}$

Let the expenditure and the saving of a family be 7x and 3x respectively.

so, expenditure = 6300

=> 7x = 6300

=> x = $\frac{6300}{7}$

=> x = 900

Now,

The savings = 3x

=> Savings = Rs (3 × 900)

=> Savings = Rs 2700

Therefore,

Total income = expenditure + savings

=> Rs ( 6300 + 2700 )

=> Rs 9000
