when you see the table 'friendList'
To calculate rating for Varun:
in first row Varun is in receiver column so i check the value in receiverRated for 1st row . i.e 4

Then in third row varun is the sender so I check the rating for varun in SenderRated column for this row . i.e 2

Then I add the ratings and divide by the count of the rates
i.e. 4+2/2
