Best way to approach such question is to eliminate what we do not need and save time. Since the question is looking for beverage consumption we do not need to look at the graph for other two items i.e. Packaged food and Prepared food.
This is not an official question because there is a margin of error possibility between option C and D and it really depends on the eyes of the test taker. See how revenue for beverage for Store B can easily be interpreted as
26% rather than
25%.
Coming to the question:
Let us assume each store makes a sale of equal amount, take
$100 for easy computation.
That makes beverage sales by 4 store as
$30,
$25,
$40,
$45Bringing the % share of beverage as: \(\frac{140}{400}\) *
100 =
35%
