Who will give the answer I'll mark him/her as brainlist..

Answer:
We will be using Average function of Excel Calculation sheet.
Its Syntax in Calc sheet is : =AVERAGE (number1, [number2], ...)
or you can use =Average and then click on the first cell and drag the whole row till end and close the brackets. It will calculate the average of that row.
Once you have applied average function on first row, you can drag this cell down the column and it will replicate the same function for respective rows.
