A man spends 12% of his income on food, 18% on children’s education, and 70% of the remaining on house rent. What percentage of his income is he left with?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 21%.
Total income = 100%
Total spent = 12% + 18% = 30%
Remaining income after Food & Education = 100% – 30% = 70%
Spent on House Rent = 0.7 × 70 = 49%
Food + Education + Rent = 30% + 49% = 79%
Final remaining income = 100% – 79% = 21%
