Roma spends 25% of her income on food, 15% on children's books, and 75% of the remaining income on uniforms. What is the percentage of income she is left with?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 15%.
Let Roma's total income = 100
Spending on food = 25
Spending on children's books = 15
Remaining income = 100 - 25 - 15 = 60
Amount spent on uniforms = (75/100) × 60 = 45
Income left = 60 - 45 = 15
Percentage of income left = (15/100) × 100 = 15%
