Question

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?

• A. 2,63,000
• B. 2,62,500
• C. 1,89,000
• D. 1,88,500

Answer 1

The correct option is B

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 $\times$ 10,500 = 2,62,500 [1 brick = 10,500].
