Question
What is the difference between the number of chocolates
distributed in class II and IV together and the number of chocolates distributed in class III and V 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 II and IV together = (15 + 18)% of 2500 = 825 Number of chocolates distributed in class III and V together = (25 + 32)% of 2500 = 1425 Required difference = 1425 – 825 = 600
