Unfortunately the answers are given at the end of the article, so you might want to use this cut-down version:
Shoppers 'fail to spot cheapest deals'
Most grocery shoppers are unable to identify the cheapest deals when faced with a blizzard of "special offers" in stores, financial experts say.
The Money Advice Service asked just over 2,000 consumers to select the best value deals from four sets of offers. Only 2% of those asked answered all four questions correctly.
In the survey, 76% of those asked said they spent more than they intended, after being enticed by special offers, paying an average £11 extra per shop.
Later on Thursday, Sainsbury's announced that it would phase out multi-buy promotions by August 2016. Sainsbury's Marketing Director, Sarah Warby said customers had told them they found multi-buy promotions "confusing" and created "logistical challenges at home in terms of storage and waste." The government-backed Money Advice Service said shoppers should look at the price per unit to compare costs. It also suggested making, and sticking to a shopping list.
The Money Advice Service tested shoppers with the following questions (answers at the bottom)
