A man spends 30% of income on rent, 25% of remainder on food, 20% of remainder on education, saves Rs. 12600. Income: MCQ with Answer and Explanation

Explanation:
Let B's salary be 100. A's salary = 125. B is 25 less than A. Percentage = (25 / 125) * 100% = 20%.

Explanation:
Wife 20%, left 80%, son 25% of 80%=20%, daughter 60%=6000 → total=10000.

Explanation:
Let boys = 60, girls = 40. Total = 100. Adult boys = 20% of 60 = 12. Adult girls = 25% of 40 = 10. Total adults = 22. Non-adults = 100 - 22 = 78. Percentage = 78%.
