Answer:
It is $60,000 (C)
Explanation:
As at 2016 :
Operating Profits =$800,000- $600,000
=$200,000.
At at 2017
Operating Profit = (800,000+100,000) -(600,000+40,000)
=900,000-640,000
=$260,000
Increase in Operating Profit = $260,000- $200,000.
=$60,000
This represents increase of [ (60,000/200,000)*100% ] 30%
