$\huge{\mathbb{\purple{A{\pink{N{\green{S{\blue{W{\red{E{\orange{R}}}}}}}}}}}}$

(a) 3:1

(b) 4:3

(c) 4:1

Explanation:

The given two things are :

Total income of the person = ₹ 60,000 per month .

His monthly expenditure = ₹ 45,000 .

$\implies His \:savings\: = Total\: income\: - Monthly\: expenditure .\\\implies His\:savings\: = 60,000\: - \: 45,000\: Rupees .\: =\: 15,000\: Rupees .$

(a) The ratio of expenditure to his savings = $\frac{Expenditure}{Savings} \: = \: \frac{45000}{15000} \: = 3:1$

(b) The ratio of income to his expenditure = $\frac{Income}{Expenditure} \:= \: \frac{60000}{45000} \:=\: 4:3$

(c) The ratio of income to his savings =$\frac{Income}{Savings} \:=\: \frac{60000}{15000}\:=\: 4:1$
