Business calcualtion on numeracy and analytical skills

Hello Sir, i am a university and acca student and i have this question as an exams but could not solve it.
I am really confused about this question , please i want you to help find the actual profit maybe for 2013 and and the revenue & budgeted expense for year 2016 then i can be able to use your tactics to get year 2014 and 2015.

If you see 2016, budgeted revenue and budgeted expenses figure were not given and we are asked to search for the likely profit and to express the result in standard form

This is the question below:

The following table shows the revenue and expenses of DYI Stores Ltd, a high street chain selling DYI goods.
