A Pie Chart is a pictorial representation of a numerical data by non intersecting adjecent sectors of the circle such that area of each sector is proportional to the magnitude of the data represented by the sector.
(a) The whole circle represents the total and the sectors, individual quantities.
(b) The sectors, are made considering the fact that the central angle is 360°
(c) The central angle, 360 ° can be divided in the ratio of quantities given.
(d) Central angle or Angle of the sector is :
The number of students studying in different faculties in the years 2001 and 2002 from state A is as follows
Ex. In which faculty there was decrease in the number of students from 2001 to 2002 ?
(a) Arts (b)Agriculture (c) Pharmacy (d)None (e) None of these
Solution : For Arts, Number of students in 2001 and 2002
For Agriculture Number of students in 2001 and 2002
For pharmacy % is already more and total number of students are already more in 2002, so correct option will be for Agriculture,option (b) is true
Ex. What is the ratio between the number of students studying pharmacy in the years 2001 and 2002 respectively ?
(a) 4 : 3 (b) 3 : 2 (c) 2 : 3 (d) 7 : 12 (e) None of these
Solution : Ratio between the number of students studying pharmacy in the years 2001 and 2002 =
Option (d) is true
Ex. What was the approximate percentage increase in the number of students of Engineering from the year 2001 to 2002 ?
(a) 17 (b) 15 (c) 25 (d) 23 (e) 20
Solution : Number of engineering students in 2001 =
Number of engineering students in 2002 =
Total increase = 7600 - 6300 = 1300
Ex. In the year 2001, the number of students studying Arts and Commerce together is what percentage of the number of students studying these subjects together in 2002 ?
(a) 76 (b) 85 (c) 82 (d) 79 (e) None of these
Solution : Number of students studying Arts and Commerce together in 2001 =
Number of students studying Arts and Commerce together in 2002 =
So, option (b) is true
