The pie chart shows the number of pens, highlighters, correction tapes 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 less highlighters than pens are sold?


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

Bar 4 is the tallest bar. It is the number of pens.
Number of pens = 30

Bar 2 is the second shortest bar. It is the number of correction tapes.
Number of correction tapes = 12

Bar 3 is the second tallest bar. It is the number of staplers.
Number of staplers = 24

Number of less highlighters than pens sold
= 30 - 6
= 24

Answer(s): 24
