• A. 2:1
• B. 4:3
• C. 3:2
• D. 8:5

Answer 1

The correct option is B 4:3

Let 100x and 100y be the total sales value and total sales volume. The values from the graph can be deduced as:

$\begin{array}{cccccccc}& LC& TO& PG& RA& IM& TP& \\ \text{Sales Value}& 30\%& 14\%& 9\%& 28\%& 10\%& 9\%& \\ \text{Sales Vol}& 20\%& 21\%& 16\%& 21\%& 10\%& 12\%& \\ & & & & & & & \\ \text{Selling Price}& & & & & & & \\ & & & & & & & \\ SP& 72& 32& 27& 64& 48& 36& \\ \text{Case I}& \text{Vit B}& \text{Iron}& \text{Vit A}& \text{Calcium}& \text{Vit K}& \text{Vit E}& \\ \text{Case II}& \text{Calcium}& \text{Vit K}& \text{Vit A}& \text{Vit E}& \text{Vit B}& \text{Iron}& \\ & & & & & & & \end{array}$
Case II is possible. The required ratio is 36:27 = 4:3.
