Solution:

Apprroximate per cent increase or decrease in production from the previous year for SIO are as follows :

2010 =

\frac{2}{85} \times 100

= 2.35 % ; 2011 =

\frac{2 \times 100}{87}

= 2.29 %

2012 =

\frac{2 \times 100}{89}

= 2.24 % ; 2013 =

\frac{1 \times 100}{91}

= 1.09 %

2014 =

\frac{4 \times 100}{92}

= 4.35 %

Quicker method : See the difference of produced units between two consecutive years. The difference is maximum for 2013 to 2014, and production during all these years is almost same. Hence, in the year 2014, SIO registered maximum increase in production over the previous year.
