Answer 1       (Option B)

Sales Value = Sales Volume × Average Price per Unit

Total Market Size :-

= Sales Value of Company X /Market Share (in %) of company X × 100

Question is asking for size of domestic market (in Rs.). Out of three different data sets given in the question (a pie chart, a line chart and a bar chart), we have Rupees value in only one data set – Bar chart. In pie chart and line chart, we do not have any information in Rupees Terms. So to answer any question in Rupees terms, we need to use Chart 3 – Bar Chart.

How do we calculate the size of domestic watch market:

Chart 1 provides the market share in sales volume in 2010. Chart 2 provides the sales volume of Titan from 2008 to 2012.

Using chart 2, Sales volume of Titan in 2010 = 32 million units and using chart 3, average selling price = Rs. 900/watch. So, total market value for Titan in 2010 = 32 million units × Rs. 900/watch = Rs. X (Assume) [we are not required to calculate this value as question is only asking for the possibility of market size calculation].

Now using chart I, market share of Titan is known = 38% = Rs. X. Using this, we can calculate 100% = Total market size of domestic watch market.

Hence it is possible to calculate only for the year 2010. We do not have Average Selling Price of Titan for the year other than 2010. So we can’t calculate the domestic market size for any year other than 2010.

Hence option B is the correct answer.

Answer 2       (Option B)

Answer 3      (Option D)
Now this is no brainer. You just have to calculate the percentage growth in the number of units sold of Titan.
2012 saw the minimum growth rate = 4.6%. Hence, option D is the answer.

Answer 4   (Option B)

Using the data from Answer 1,
So, total market value of Titan in 2010 = 32 million units × Rs. 900/watch = Rs. 28800 million
Titan has a market share of 38% in 2010.
Hence 38% = Rs. 28800 million
100% = Rs. 75789.47 million = Rs. 7578.9 crores
Hence, option B is the answer.
