The pie chart shows the number of three types of pens sold by a stationery shops last week. Which bar graph best represents the information in the pie chart? Give your answer in number. (Eg Bar Graph 1 = 1)








The pie chart has 4 pie slices of different sizes. There must be 4 vertical bars of different height.

Bar Graph 1
There are 2 vertical bars with equal height.  They represent the 2 pie slices that are right angles (90°). 
The other 2 vertical bars have unequal heights, one taller than the other.
