Explanation:

From the above table,
The number of students are available in college A$$ = 950$$
The number of students are available in college B $$= 1200$$
The number of students are available in college C $$= 850$$
The number of students are available in college D $$= 975$$
The number of students are available in college E $$= 1025$$
Hence, total number of students are available in the class $$= 5000$$
so percentage of area occupy by college B $$\dfrac{1200\times 100}{5000}=24\%$$
which occupy 24% of the area in the pie graph.
