Explanation:

Let monthly salary be Rs. 100.
Remaining salary after spending 40% of his monthly salary on house rent = 100 – 40 = Rs. 60
Remaining amount after spending 25% of the remaining salary on food = 60 – (25% of 60) = Rs. 45
Given that annually saving = Rs. 48600
Then, monthly saving = Rs. 48600 ÷ 12 = Rs. 4050
Now, 45 : 100 : : 4050 : x
∴ x = 100 x 4050/45 = 9000
