Correct Answer - Option 2 : 20 percent
Given:
Naman spends 25 percent of his income on food and 35 percent on children's education and 50 percent of the remaining part on house rent
Calculation:
Total income spend on food and children's education = 25 + 35 = 60%
Income spent on house rent = 50% of 40% of the income = 20%
∴ Income left = 100 - (60 + 20) = 20%
