The pie chart shows the number of foolscaps, pencils, highlighters and staplers sold by a shop. The same information is shown in a bar graph, but the names of the items are not shown on the bar graph. How many more staplers than highlighters are sold?


Bar 1 is the shortest bar. It is the number of pencils.
Number of pencils = 6

Bar 2 is the tallest bar. It is the number of foolscaps.
Number of foolscaps = 37

Bar 3 is the second tallest bar. It is the number of staplers.
Number of staplers = 32

Bar 4 is the second shortest bar. It is the number of highlighters.
Number of highlighters = 11

Number of more staplers than highlighters sold
= 32 - 11
= 21

Answer(s): 21
