Given:
- A person spends 75% of his income.
To find:
- Percent increase in his saving when his income increases by 20% and expenses increase by 15%.
Solution:
Step 1: Calculate the person's current saving:
- Since the person spends 75% of his income, he saves 25% of his income.
- Let's assume his current income is $100.
- Therefore, his current saving is 25% of $100, which is $25.
Step 2: Calculate the person's new income and expenses:
- If his income increases by 20%, the new income will be $100 + (20% of $100) = $100 + $20 = $120.
- If his expenses increase by 15%, the new expenses will be 75% + (15% of 75%) = 75% + 11.25% = 86.25%.
Step 3: Calculate the person's new saving:
- The new saving will be the difference between the new income and new expenses.
- New saving = 100% - 86.25% = 13.75%.
Step 4: Calculate the percent increase in saving:
- Percent increase in saving = (new saving - current saving) / current saving * 100.
- Percent increase in saving = (13.75% - 25%) / 25% * 100 = -45%.
- The negative sign indicates a decrease in saving instead of an increase.
Conclusion:
- When the person's income increases by 20% and expenses increase by 15%, his saving decreases by 45%.
- A person spends 75% of his income.
To find:
- Percent increase in his saving when his income increases by 20% and expenses increase by 15%.
Solution:
Step 1: Calculate the person's current saving:
- Since the person spends 75% of his income, he saves 25% of his income.
- Let's assume his current income is $100.
- Therefore, his current saving is 25% of $100, which is $25.
Step 2: Calculate the person's new income and expenses:
- If his income increases by 20%, the new income will be $100 + (20% of $100) = $100 + $20 = $120.
- If his expenses increase by 15%, the new expenses will be 75% + (15% of 75%) = 75% + 11.25% = 86.25%.
Step 3: Calculate the person's new saving:
- The new saving will be the difference between the new income and new expenses.
- New saving = 100% - 86.25% = 13.75%.
Step 4: Calculate the percent increase in saving:
- Percent increase in saving = (new saving - current saving) / current saving * 100.
- Percent increase in saving = (13.75% - 25%) / 25% * 100 = -45%.
- The negative sign indicates a decrease in saving instead of an increase.
Conclusion:
- When the person's income increases by 20% and expenses increase by 15%, his saving decreases by 45%.
