Answer:
This is a pie chart problem where every sector represents some value out of total value depending upon central angle.
given total student = 3000
we have to find number of students interested in English.
For this, we need to know the central angle for English which is not given in figure, so we have to derive it.
Total value of central angle is always = 360°
36° + 90° + 126° + English = 360°
252° + English = 360°
English = 360° - 252°
English = 108°
number of student interested in English
= (108°/360°)*3000
= 900
