Bar 2 is the shortest bar. It is the number of foolscaps.
Number of foolscaps = 10

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

Bar 1 is the second shortest bar. It is the number of correction tapes.
Number of correction tapes = 14

Bar 3 is the second tallest bar. It is the number of highlighters.

= 30 - 10
= 20
