Choose the correct order for graphene production via Ion implantation.

Choose the correct order for graphene production via Ion implantation. Correct Answer Application of electric field ➜ Acceleration of carbon ions onto substrate ➜ High temperature activation annealing ➜ Creation of graphene layer

Graphene can be created on silicon using ion implantation method. In this process carbon ions are accelerated, by an electric field, onto a layered surface comprising of nickel, silicon dioxide and silicon. The nickel layer acts as a catalyst for graphene synthesis and has high solubility for carbon. The process then involves high temperature activation annealing to form a honeycomb lattice of graphene on the substrate.

The given bar graph represents data of the production of paper (in ten lakh tonnes) by three different companies X, Y and Z during the years 2008 to 2012. The x-axis shows the 'years' and the y-axis represents the 'production of paper (ten lakh tonnes)'. (Note: The data shown is only for mathematical exercise. They do not represent actual figures.)  The total production of Company Y during 2008 and 2009 and Company X for 2011 and 2012 taken together is p% (p is correct to the nearest integer) more than the total production of Company Z during 2010, 2011 and 2012. The total production of Company Z during 2008 and 2009 taken together is q% (q is correct to the nearest integer) less than the total production of Company X during 2008, 2009 and 2012 and Company Y during 2010 and 2011 all together.  What is the positive difference between p and q ?
