“You are William Playfair!!!” Jack exclaimed with super surprise. “Yes, I am”, he replied. While Jack was still in the state of astonishment, William asked him, “Can you help me again? I have a list of number of people who have attended the Mass and lunch offered at the church for four months. Can you help me compare this data?” According to his list, then, Jack drew a bar chart (which William doesn’t know anything about). It came as:
Looking at this, William exclaimed - “What a nice chart! We can easily compare the number of people. Thanks” Then Jack smiled and said- “If it’s that easy, tell me in which month the number of people attending Mass is maximum and in which month the number of people attending lunch is minimum?” The correct answer is –
April and March
As seen from the graph, the month in which maximum number of people attended the mass prayer is in April because the blue bar is longest for the month of April. Similarly, the month in which minimum number of people attended lunch is in March because the orange bar is shortest for the month of March.
