a part:) how do we get the figures under Revenue 14378 -Q2,14666 Q3 and so on.. as well as for Cost of sales how do we get the figures -8914,-9093 and so on ..
If you look at the budget given in the question, the revenue is increasing by 2% each quarter. Applying 2% growth to the actual revenue in Q1 gives 14,096 x 1.02 = 14,378 for Q2; 14,378 x 1.02 = 14,666 for Q3, and so on.
Similarly, the cost of sales in the previous year were growing at 2% per quarter. So the actual cost of sales in Q1 is increased at 2% per quarter.
