Total number of students in a class
= Number of boys + Number of girls present in that class
From the double bar graph,
Total number of students in VII-A = 20 + 15 = 35
Total number of students in VII-B = 25 + 30 = 55
Total number of students in VII-C = 15 + 20 = 35
Total number of students in VII-D = 25 + 20 = 45
total number of students in VII-E = 20 + 25 = 45
