A man invested 25% of his monthly income on food. From the remaining amount, he spends 20% on rent. If he then spends 20% of the remaining income on education and saves ₹19,200, what is his monthly income?

1. 30000
2. 50000
3. 60000
4. 40000

Correct answer: 40000

Solution

He spends 25% on food, leaving 75%. Then 20% of that is spent on rent, leaving 80% of 75% = 60%. Then 20% of the remaining is spent on education, leaving 80% of 60% = 48% of the original income. Since 48% equals ₹19,200, the income is ₹40,000.
