On analyzing the question,
For Option A, if we consider the first statement alone it is insufficient as we do not know the proportion of overall brands per se. Hence we can eliminate option A & by default we can eliminate option D as well.
Similarly for option B if we only consider the second statement alone, we only know the proportion of brands that raised their price by at least 2 dollars. Hence option B is also insufficient & hence can be eliminated.
On combining both the statements together,
If we assume brands that increased their price to be B & assume the total number of brands to be T, we can say that 25% of B = 15% of T as it represents the same value (total number of brands that increased their price by at least 2 dollars),
Hence B/T = 15/25=3/5 = 60% Since we wanted to know the percentage of total brands that increased their wholesale price as indicated by B/T. Option C is sufficient to answer this question
Hence the answer is Option (C) Both statements together are sufficient

At a recent trade show, a survey was conducted on coffee brands. Each brand was categorized based on whether it increased its wholesale price per pound this year compared to last year.
Let, percentage of the brands surveyed increased their wholesale price this year= x
(1) Of the brands that increased their price, 25% increased it by at least $2 per pound.
It only provides information about a subgroup. So it is insufficient to answer the question.
(2) Of all the brands surveyed, 15% increased their price by at least $2 per pound.
Some brand increased their price by atleast $2 per pound and other might have increased less but still increase the price, no information is provided about those brands. So insufficient
From (1)&(2)
0.25*x=15%
x=60%
Sufficient to answer

% surveyed who increased prices=X%
St 1
no info about surveyed or proportion of surveyed who increased prices. No sufficient
St 2
Of surveyed, 15% increased by at least 2 pound. No info if 85% remaining increased by less that 2 pound or no increase. Not sufficient
St 1 and 2 together-
Let total who increased prices=100, 25 of these increased by 2 or more pound. 75 by less than 2 pound. Let surveyed=60, 9 of these increased by 2 or more. Again no info that remaining 51 are increased >0and <2 or no change.
