Solution

Here, the white colour bars represents the performance in the year 2005-06 and the grey colour bar represents the performance in the year 2006 - 07.

The difference between the heights of the white bars and the grey bars tell us the improvement in performance. The greater the difference, the more substantial the improvement is. $[1]$

From the double bar graph, we observe that the maximum increase in the length of bar from previous year to the next year is for Maths.

Therefore, the students have improved the most in Maths. $[1]$
