In the following pie chart, the percentage distribution of students in different courses are shown. What is the total number of students in B.Ed., Pharmacy and MBBS together? Total number of students =6800
2645
2516
2428
2145
2516
Given: Total students = 6800. Percentages: B.Ed = 18%, Pharmacy = 13%, MBBS = 6%.
Total students = 6800. Percentages: B.Ed = 18%, Pharmacy = 13%, MBBS = 6%.
Total=(100P1+P2+P3)×Total Students
Sum the percentages (18 + 13 + 6 = 37%) and multiply by 68. Since 6800 / 100 = 68, just calculate 37 × 68 = 2516.
Adding percentages incorrectly or misreading the pie chart segments leading to calculation errors.
Identify individual percentages
From the pie chart, the percentages for the requested courses are: B.Ed = 18%, Pharmacy = 13%, and MBBS = 6%.
Ptotal=18%+13%+6%=37%
Calculate total number of students
Apply the total percentage of the three courses to the overall student population of 6800.
Students=10037×6800
Perform final multiplication
Multiply 37 by 68 to find the total count.
37×68=2516
B is correct because the sum of percentages for B.Ed (18%), Pharmacy (13%), and MBBS (6%) is 37%, and 37% of 6800 is 2516.
This concept of percentage distribution is frequently used in Data Interpretation (DI) sections of competitive exams to save time by summing percentages before multiplying.
