Question

In a pie chart if marks of students im maths are represented by an angle of 270°. Find the percentage of marks

Answer 1

A total rotation means angle of 360°
Here it is 270°

so we have to find how much percent is 270 of 360
let the required percentage be x
therefore
$360 \times \frac{x}{100} = 270$
x=270 / 3.6

x=75

thus the percentage of marks is 75%hope it helps
