The table given below shows the income and expenditure of a company in five years.
| Years | Income | Expenditure |
| A | 350 | 150 |
| B | 250 | 100 |
| C | 200 | 150 |
| D | 400 | 100 |
| E | 150 | 75 |
Saving = Income - Expenditure
What is the average saving in all years?
Answer & explanation
Correct answer: option 4
Total saving of all years = (350 - 150) + (250 - 100) + (200 - 150) + (400 - 100) + (150 - 75)
= 200 + 150 + 50 + 300 + 75
= 775
Average = \(\frac{775}{5}\)
= 155
