Question
Find the average number of chocolates distributed in
class IV, V and VI together. Study the following line chart carefully and answer the questions given below: The following pie chart shows the percentage distribution of chocolates to the students studying in five different classes (i.e. II, III, IV, V and VI) Total number of chocolates = 2500Solution
Number of chocolates distributed in class IV = (18/100) × 2500 = 450 Number of chocolates distributed in class V = (32/100) × 2500 = 800 Number of chocolates distributed in class VI = (10/100) × 2500 = 250 Required average = (450 + 800 + 250)/3 = 500
