Numerical Reasoning - graph

The answer is 25% decrease. From the graph, I eliminated the 4 answers because the graph for "food and beverages" and "services" has decreased.

Why is it 25%? For example, food & Beverages went from 60 Million to 50 Million and Services went from 20 million to 10 million. I wanted to say... what percentage of 50 million is less than 60 million...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Non-Accommodation Revenue in 2010: 60 Million(FnB) + 20 Million(Services) = 80 Million
Non-Accommodation Revenue in 2015: 50 Million(FnB) + 10 Million(Services)= 60 Million

Change from 2010 to 2015 = 80 Million - 60 Million = -20 Million

Percentage Change as compared to 2010 = -20 Million *100 / 80 Million = -25%
