Calculation:

According to the question,

Average expenditure on Delivery from 2002 to 2006 = (Total expenditure on Delivery from 2002 to 2006)/(Number of years)

⇒ (40000 + 45000 + 55000 + 55000 + 75000)/5

⇒ 270000/5

⇒ 54000

again, According to the question,

Average expenditure on Interest from 2002 to 2006 = (Total expenditure on Interest from 2002 to 2006)/(Number of years)

⇒ (40000 + 35000 + 55000 + 45000 + 50000)/5

⇒ 225000/5

⇒ 45000

So, The required percentage = {(Average expenditure on Delivery - Average expenditure on Interest)/Average expenditure on Interest} × 100%

⇒ {(54000 - 45000)/45000} × 100%

⇒ (9000/45000) × 100%

⇒ 1/5 × 100%

⇒ 20%

∴ The average expenditure on Delivery is more than the average expenditure on Interest by 20%.
