Answer:

₹ 4500

Given:

Ratio of the income to expenditure of a family is 10:7 and family's expenses are ₹10500

To find:

The savings of the family

Solution:-

Let ratio of family's income to expenditure be 10x and 7x

We know that

Savings=Income-Expenditure

=10x-7x

=3x

Expenditure is ₹10500=7x

x=10500/7

x=1500

Expenditure=₹1500

Savings=3x

=3×1500

=₹ 4500

--------------------

Therefore, savings of family ₹4500

Answer 2

Answer:

Suppose ratio of family income to expenditure = 10x and 7x

Formula of saving= Income - Expenditure

= 10x - 7x

= 3x

Expenditure = Rs 10500 = 7x

x = 10500/7

x = 1500

Expenditure = Rs 1500

Savings = 3x

= 3 × 1500

= Rs 4500.
