This table shows the number of students studying in various streams in different colleges.
If the data about students of the commerce stream in all colleges is represented by a pie-chart, what is the central angle of the sector representing college D, to the nearest degree?
In pie chart $$360^\circ$$=100% and 1% =Â $$\frac{18}{5}\ \ or\ \ 3.6^{\circ}$$
Total students of commerce = 480+520+350+520+330=2200
central angle of the sector representing college D=Â $$\frac{520}{2200}\times\ 100\times\ 3.6=85\%$$
