A lady spends 20 percent of her total income on house rent, and 75 percent of the rest on household items. If she saves Rs 600, then what is her income?
Show answer & explanation
Correct answer: D
Explanation
The Correct answer is option 4 i.e. Rs 3,000.
Let the total income of a lady be 100 units
Given that
The expenditure on house rent = 20% of Income = (20/100) × 100 = 20 units
The remaining income = 100 - 20 = 80 units
The spend on household items = 75% of 80 units = (75/100) × 80 = 60 units
Now, Her savings = 80 - 60 = 20 units
Her savings given is Rs 600
⇒ 20 units = 600
⇒ 1 unit = 600/20 = 30
⇒ 100 units = 30 × 100 = Rs 3000
Hence, Her total income is Rs 3000
