A man spends 75% of his income. Due to inflation, his expenses increase by 20%, and his income increases by 10%. What is the percentage change in his savings?

1. 30% decrease
2. 40% decrease
3. 10% decrease
4. 20% decrease

Correct answer: 20% decrease

Solution

If income is 100, expenses are 75 and savings are 25. After a 10% income increase, income becomes 110; after a 20% expense increase, expenses become 90. New savings = 110 - 90 = 20, which is a 20% decrease from 25.
