Solution

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 × 10,500 = 2,62,500 [1 brick = 10,500].
