I saw this puzzle in a newspaper today. I know the answer because it was given but I cannot see how to work it out, other than by trial and error, as there does not seem to be enough information.
Some belts were sold at £14.95
The price was reduced to £13.95 and some more were sold.
The price was reduced again to £12.95 and some more were sold.
The total amount taken was £299.95.
How many belts were sold altogether?
