The Table given below presents the profit (in multiple of thousand rupees) of a firm for the years 2010-2018. By how much percentage is the average profit of years 2015-2017 greater than the profit of 2012?

25

⇒ Average profit of years 2015-2017 = \(\frac{11000+8000+11000 }{3}\)

= \(\frac{30000 }{3}\)

= 10000

⇒ Profit of 2012 = 8000

⇒ Required percentage = \(\frac{10000 - 8000 }{8000}\) × 100

= \(\frac{1 }{4}\) × 100

= 25%
