The table given below shows the saving and expenditure of 5 companies.
| Companies | Savings | Expenditure |
| J | 400 | 200 |
| K | 900 | 500 |
| L | 700 | 400 |
| M | 400 | 300 |
| N | 500 | 1100 |
The total expenditure of all the companies is how much percent less than the total savings?
Answer & explanation
Correct answer: option 4
Total expenditure = 200 + 500 + 400 + 300 + 1100 = 2500
Total saving = 400 + 900 + 700 + 400 + 500 = 2900
Required percentage = \(\frac{2900 - 2500}{2900}\) × 100
= \(\frac{400}{2900}\) × 100
= 13.79%
