Question

A pie diagram of the marks secured by a student in Maths, English, Physics and Chemistry is shown here Read the graph and find the marks in Chemistry secured by the student.​

Answer 1

Marks secured in Chemistry is 68.

Given:

A pie chart

To find:

Marks in chemistry

Solution:

From the figure we can see that both maths and physics have 100⁰.

Therefore both marks are same. Hence Physics marks = 80

Angle for chemistry is

100⁰ + 75⁰ + 100⁰ + chem = 360⁰

So chem = 85⁰

For 100⁰ it is 80 marks.

Hence for 85⁰ marks =  $\frac{85}{100}$ x 80 = 68

Therefore marks secured in Chemistry is 68.
