Out of the following which type of battery achieved highest growth between the years 2006 and 2012?
1. Type V
2. Type III
3. Type II
4. Type I

Answer 1

Correct Answer - Option 4 : Type I

From the given table, we can see that only in type I, type III and type V there is growth between 2006 and 2012.

Sales of type I battery in 2006 = 75

Sales of type I battery in 2012 = 115

Growth of type I battery \(= \frac{{115 - 75}}{{75}} \times 100\% = 53.33\% \)

Sales of type III battery in 2006 = 114

Sales of type III battery in 2012 = 160

Growth of type III battery \(= \frac{{\left( {160 - 114} \right)}}{{114}} \times 100\% = 40.35\% \)

Sales of type V battery in 2006 = 108

Sales of type V battery in 2012 = 145

Growth of type V battery \(= \frac{{145 - 108}}{{108}} \times 100\% = 34.26\%\)

Hence we can see that the highest growth in sales is of the type I batteries.
