Actual angle made by all the students (Number of students = 720) at the centre of the circle = 360°
Measure of the central angle of the sector representing the Electrical course
⇒ 160 × (360°)/720 = 80°
∴ Required answer = 80°
Shortcut TrickHere, Ratio of Electrical course : Total students
⇒ 160 : 720 = 2 : 9 = 2/9
Here, 9 units = 360°
⇒ 1 units = 40∘
⇒ 2 units = 80∘
