Answer 1

Total Expenditure - 9800 - 70%

Savings - 4200 - 30%

10% is 1400

Total Income - 14000

Answer 2

Answer: The monthly income of his family is Rs. 140000.

Step-by-step explanation:

Since we have given that

Total expenditure = Rs. 9800

Let the monthly income be 'x'.

Since the monthly saving of a family is 30% of the monthly income.

Monthly saving = $\dfrac{30}{100}x=\dfrac{3}{10}x$

As we know that " Expenditure = Income - Saving ":

$9800=x-\dfrac{3x}{10}\\\\9800=\dfrac{10x-3x}{10}\\\\9800=\dfrac{7x}{10}\\\\\dfrac{9800}{7}=\dfrac{x}{100}\\\\1400=\dfrac{x}{100}\\\\x=1400\times 100\\\\x=Rs. 140000$

Hence, the monthly income of his family is Rs. 140000.
