What a relief when we reach home after crossing all the obstacles and jumping over the head of several toads and turtles! Here is a histogram which is made up of bricks. 1 brick = 10,500 CDs sold. Carefully observe the histogram and answer the questions that follow:
What is the no. of CDs sold during the period 2008 - 2013?
2,62,500
The height of the histogram gives the frequency of an entry. This means that every time a CD is sold, an entry is made into a table (Frequency distribution table). Hence, the no. of CDs sold will be equal to the frequency i.e. height of the histogram. During 2008-2013, it is 3+4+5+6+7 = 25 bricks.
So, 25 × 10,500 = 2,62,500 [1 brick = 10,500].
