Tips, Tricks and Shortcuts 

Pie charts are a common type of data visualization used in data interpretation.
Here are some tips and tricks to solve pie chart questions:

  • Read the data in the pie chart carefully: If the distribution is given in percent, simply multiply this value to the total amount of data and then divide by 100 to get the actual value.
  • Remember that a whole circle contains 360 degrees: In a pie chart, each sector represents a certain percentage of the total data, which can be calculated using the formula: percentage of a data = (given data/total of all data) x 100.
  • Calculate the central angle of each sector using the formula: central angle of a data = (given data/total of all data) x 360 degrees.
  • Practice solving pie chart questions with solutions and explanations.

Uses of Pie Chart

Pie charts are a type of chart used to represent fractions as parts of a whole. They are commonly used to compare data and analyze which data is bigger or smaller. Pie charts are preferred when dealing with discrete data.

Q1: The difference of marks scored in Social Science and Science by students of G.D.Goenka School is

 (a) 37.5
 (b) 40
 (c) 20
 (d) 15
Ans:
a
Sol: Angle of Science sector is 80ºand angle of Social Science sector is 65º. So difference of angle is 15º. Difference of marks = (15º x 900 ) / 360º = 37.5


Q2: The Marks scored by the student of G.D.Goenka School in English and Mathematics is less than the marks scored in Science and Hindi by
(a) 5%
(b) 4.33%
(c) 3.33%
(d) 6%
Ans:
c
Sol:
Marks scored in English and Mathematics = (55 + 90 ) / 360 x 900 = 362.5
Marks scored in Hindi and Science = (70 + 80) / 360 x 900 = 375
Percent decrease = 12.5 / 375 x 100 = 3.33


Q3: What are total marks scored in Social Science and English by students of G.D.Goenka School?
(a) 300
(b) 350
(c) 400
(d) 450
Ans:
a
Sol: Angle of English sector is 55º and angle of Social Science sector is 65º. So sum of angles is 120º. Sum of marks =( 120º x 900) / 360 = 300. 

Q4: If the total marks of student of G.D.Goenka School were 3000, then marks in Mathematics would be
(a) 800
(b) 750
(c) 850
(d) 900

Ans: b
Sol: Marks obtained in Mathematics would be = 90 / 360 x 3000 = 750


Q5: If the marks scored by the student of G.D.Goenka School are 137.5, then the subject is
(a) English
(b) Hindi
(c) Mathematics
(d) Science
Ans: a
Sol: Going by the options, marks scored in English = 55 /360 x 900 = 137.5
