Which vinegar listed containing a certain percentage of acetic acid is the best value for money?

Question

1. 4.73% of acetic acid in the vinegar for £0.83
2. 6.19% £1.15
3. 5.04% £1.15
4. 5.21% £3.00
5. 5.13% £0.50
6. 6.1% £1.50

Answer 1

To find the answer you need to calculate % acetic acid per pound (or is it quid?)

So, just do the divisions:

 

4.73/.83 = 5.7% per pound

6.19/1.15 =5.38% per pound

obviously #3 will be less than # 2

obviously #4 will be less than # 2

5.13/.5 = 10.26%

no need to check the rest.  # 5 gives you best value per unit of money.
