The pie chart shows the number of highlighters, pens, correction tapes and post-it pads 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 less pens than highlighters are sold?


Bar 1 is the shortest bar. It is the number of pens.
Number of pens = 2

Bar 4 is the tallest bar. It is the number of highlighters.
Number of highlighters = 39

Bar 2 is the second shortest bar. It is the number of correction tapes.
Number of correction tapes = 10

Bar 3 is the second tallest bar. It is the number of post-it pads.
Number of post-it pads = 31

Number of less pens than highlighters sold
= 39 - 2
= 37

Answer(s): 37
