Solution
a) Number of students participated from grade III = 10
Number of students participated from grade IV = 60
Difference = 60 - 10 = 50 students
So, 50 more students from grade IV have participated in the competition as compared to grade III.
b) Total number of students = sum of students from each class
= 30 + 50 + 10 + 60 + 30
= 180 students
Number of students participated from grade IV = 60
Difference = 60 - 10 = 50 students
So, 50 more students from grade IV have participated in the competition as compared to grade III.
b) Total number of students = sum of students from each class
= 30 + 50 + 10 + 60 + 30
= 180 students
