I'm sure it was just a typo in the title, but you will have a better chance of success if you search on Habs Boys :D

Please can you let me know how to solve this Q ?

Look carefully at the following five supermarket offers

A Buy one get one free

B Buy one get the second for half price

C Buy two get one free

D Buy four and pay only for three

E One-third of all prices

Two pairs of these offers actually give the same value for money ,write down the letters represending both of these pairs in the spaces below

----- and ---- give the same value for money

----- and ----- give the same value for money

I would choose a price and work them out - I would suggest £3 as we need to find one third.

A) £3 buys 2 ie £1.50 each
B) £4.50 buys 2 ie £2.25 each

Can you finish it now?

Try looking at them re: What do you get? What do you pay for?

For example, with option B,
- when you buy two together, you get the second at half price, so
- you get two, but only pay for one and a half
So if for example you bought four (two lots of two), how many would you have to pay for? Does this deal look like any of the others?
etc

With £12 in hand and price per item is £3 pound I get following answers

A offer will give me 8 items [ Buy one get one free] so per pound I get 2/3 of item

B offer will give me 5 items [ Buy one get the second for half price ] so per pound I get 5/12 item

C offer will give 6 items [ Buy two get one free] so per pound 1/2 item

D offer will give 5 items [ Buy four and pay only for three] so per pound 5/12 item

E offer will give 12 items [ one-third of all prices] so per pound 1 item

so my answer is only B and D will give same value for money , however I didn't get another pair of same value.

Any help ?

Yes, it might be easier to try my approach as some of your choices don't work well e.g. D

I don't think I would do it like that (sorry, Guest55 :) )

A Buy one get one free
Get two, pay for one
Get four, pay for two


B Buy one get the second for half price
Get two, pay for one and a half
Get four, pay for three


C Buy two get one free
Get three, pay for two (alternative way of saying this: pay for two-thirds of what you get?)

 D Buy four and pay only for three

E One-third of all prices 
Get three, pay for...?

Now can you see another pair?

E will be get three and pay for one. which is equal to 1/3 isn't ? sorry I'm trying to understand this but failing. Can you give me more clue ? could not do it :(
