“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 the number of people who have attended the mass prayers and lunch offered at the church. But I am facing difficulty comparing them. Can you help me to compare them easily?” 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 no. of people. Thanks” Then Jack smiled and said- “If it’s that easy, tell me in which month no. of people attending the mass prayers is maximum and in which month no. of people attending lunch is minimum?” The correct answer is –
April and March
As seen from the graph, the month in which the 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 the minimum number of people attended lunch is in March because the orange bar is shortest for the month of March.
