The pie chart shows the number of glues, post-it pads, staplers and correction tapes 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 post-it pads than glues are sold?


Bar 2 is the shortest bar. It is the number of post-it pads.
Number of post-it pads = 7

Bar 4 is the tallest bar. It is the number of glues.
Number of glues = 33

Bar 1 is the second shortest bar. It is the number of staplers.
Number of staplers = 10

Bar 3 is the second tallest bar. It is the number of correction tapes.
Number of correction tapes = 30

Number of less post-it pads than glues sold
= 33 - 7
= 26

Answer(s): 26
