Question

In come in 3 month of a person is same as his expenditure in 4 months. If his annual saving is rs.600. What is his monthly income?

Answer 1

Answer:

1800

Explanation:

Let the salary be x and expenditure be y

According to question,

1/3x=1/4y (converting months into years)

So,4 × 1/3x - 3 × 1/4 y = 600

=> 4×1/3x - 3 × 1/3 x = 600 (substituting 1/4 y = 1/3x)

=> 1/3x = 600

So, salary = 600×3

=> salary = 1800
