Question

PLEASE HELP THIS Q IS ON A QUIZ ABOUT RATIO AND PROPORTION

Answer 1

We want to see which offer is the best one to buy 40 batteries, by using algebra we will see that the best offer is offer-B

How to find the best offer?

Here we just need to see which would be the cost of 40 batteries which each offer.

For offer-A, a pack of 4 costs £2.52 and we have 1/3 off.

For 40 batteries the cost will be 10 times the above quantity, we get:

10* £2.52 =  £25.20

But there is a 1/3 off, so the cost would be 2/3 of the above quantity:

£25.20*(2/3) = £16.80

For offer-B we know that a pack of 5 costs £2.75, so you need to buy 8 of these. And for each 3 you get one free, so you need to buy 6 (and get 2 free ones). The cost of 6 of these is:

6*£2.75 = $16.50

From this, we can conclude that offer-B is the best one.
