Q7 of 11 Page 28

I have made a model. I made a chart of expenditure of buying materials.

Let’s make a pie chart with this information and write the central angle of the sectors


Firstly, we’ll covert in fraction.

The total expenditure on that day=9+12+25+6+8


=60


∴ the fraction of Art Paper



⇒ central angle=


=54°


Similarly, the fraction of sketch Pen



⇒ central angle=


=72°


And, the fraction of Scissor



⇒ central angle=


=150°


And, the fraction of Colored Paper



⇒ central angle=


=36°


And, the fraction of Pitch board



⇒ central angle=


=48°


Therefore, we can make pie-chart using these central angles.

I have made a list of things of what the students of class VIII of both the sections like to do during their leisure (one student can like only one subject).

Let’s work out from this data what fraction of the total students prefer which subjects.


Let’s find the central angle of each sector and make pie chart accordingly.

I made a list of the painters based on the perferences of 450 spectators visiting to an art exhibition on one day.

Let’s make a pie chart with this information and write central angle of the sectors.

A chart was made by asking the name of the favourite season to a group of 180 boys.

Let’s find the answer to the questions from the pie chart given below.



i. Let’s write which season is liked by most of the students and how many liked it?


ii. Let’s write which season is liked by the least number of the students.


iii. Let’s write how many students like summer.


iv. Let’s see the pie chart and make two more new questions and try to find answers to them.


(a) Let’s write how many students like spring.


(b) Let’s write how many students don’t like winter.
