Correct Answer - Option 4 : Rs. 10,000
Given:
Rita spends on house rent = 25%
On remaining income on food = 30%
Saving = Rs. 5250
Calculation:
Let the monthly salary of Rita be 100x
Amount spend on house rent = 25x
Remaining amount spend on food = 30% of 75x
⇒ 22.5x
Now, according to question
⇒ 100x – (25x + 22.5x) = 5250
⇒ 100x – 47.5x = 5250
⇒ 52.5x = 5250
⇒ x = 100
Her monthly income = Rs. (100 × 100)
⇒ Rs. 10000
∴ Her monthly income is 10000
