Question

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

Answer 1

Ratio of Expenditure to savings=7:3
Let Ratio=7x,3x
Total Income=₹(7x+3x)
Expenditure=₹6300
We know
Total Income=Total Expenditure+Savings
MEANS
7x+3x=₹6300+3x
10x-3x=6300
7x=6300
x=6300/7
x=900

Total Income
=10x+3x=10x
=10×900
=₹9000

$\boxed{\mathbf{Total\:income=Rs.9000}}$

Answer 2

Given That :-

• Expenditure : Savings = 7:3
• Expenditure = ₹6300

To Find :-

• Income

Solution :-

Let the Expenditure be 7x and the Saving be 3x

As we know that expenditure is ₹6300

So,

7x = 6300
x = 6300/7
x = 900

Now,

3x = 3 × 900
= 2700

Income = Expenditure + Savings
Income = ₹(6300+2700)
= ₹ 9000

Hence, the income is ₹ 9000
