The ratio of income to expenditure of a man is given as 7:6. This means that for every 7 units of income, the expenditure is 6 units.
To find the saving, we need to subtract the expenditure from the income. Let's calculate the expenditure first.
Given that the income is Rs 28000, we can set up a proportion to find the expenditure:
Income/Expenditure = 7/6
Cross multiplying, we get:
6 * Income = 7 * Expenditure
Substituting the value of Income as Rs 28000, we have:
6 * 28000 = 7 * Expenditure
168000 = 7 * Expenditure
Dividing both sides by 7, we find:
Expenditure = 168000/7 = Rs 24000
Now, we can calculate the saving by subtracting the expenditure from the income:
Saving = Income - Expenditure
= Rs 28000 - Rs 24000
= Rs 4000
Therefore, the saving is Rs 4000. Hence, option D is the correct answer.
Let's summarize the solution:
Summary:
- Given ratio of income to expenditure is 7:6
- Income is Rs 28000
- Expenditure can be found by setting up a proportion
- Cross multiplying, we get 6 * 28000 = 7 * Expenditure
- Expenditure is calculated as Rs 24000
- Saving is found by subtracting the expenditure from the income
- Saving = Rs 28000 - Rs 24000 = Rs 4000
- Therefore, the saving is Rs 4000, which is option D.
