    "The cost of bananas increased by 25% one week but then fell the following week back to the original price. By what percentage did the cost of bananas fall in the following week?" The answer is 20% but I don't really get how they got there...

    Say it cost 1 pound. Next week it costs 1.25. Then it goes back to 1 pound. It fell by 25p so 25p as a percentage of 1.25 is 20%
