$\underline{\underline{\textsf{Step-by-step Explanation}}}$

Given

• Ratio of expenditure to the savings of the family Is 7:3

• to the savings of the family Is 7:3And it's also given that Expenditure = ₹6300

To find

• Income Of the family

Solution

Now let the Constant of the Ratio be X

Therefore according to question,

$\longrightarrow \mathsf{Expenditure = 7x = 6300rs}$.....Eq-(1)

$\longrightarrow \mathsf{Savings = 3x = ?}$....Eq-(2)

Therefore From EQ (1) we have,

$\longrightarrow \mathsf{7x = 6300rs}$

$\longrightarrow \mathsf{x = \dfrac{6300rs}{7}}$

$\longrightarrow \mathsf{x = 900rs}$

Now putting this value X in EQ (2) we have,

$\longrightarrow \mathsf{Savings \implies 3x = 3(900) = 2700rs}$

Therefore we have,

$\longrightarrow \mathsf{Income = Expenditure\: +\: Savings}$

$\longrightarrow \mathsf{Income = 6300rs + 2700rs = 9000rs}$

Therefore Required answer Is

$\boxed{\mathsf{Income \: of \: Family \: = 9000rs}}$
