There are two options to consider giving rise to 4 possibilities
People not liking chocolate drink as well as cricket (a).
People liking cricket but not chocolate drink (b).
People liking chocolate drink but not cricket (c).
People liking both chocolate drink and cricket (d).
The sum of all these should be equal to total number of people in the office.
Thus,
a+b+c+d = 38
i.e., 20+(15-d)+(10-d)+d = 38
therefore, 45-d = 38
thus, d= 7
Thus, 7 people like both chocolate drink and cricket.

If 2 dont like both then the answer will be negative.I think there will be 20 in the place of 2.
Then the problem can be solved in the following way:

There are two options to consider giving rise to 4 possibilities

People not liking chocolate drink as well as cricket (a).
People liking cricket but not chocolate drink (b).
People liking chocolate drink but not cricket (c).
People liking both chocolate drink and cricket (d).

The sum of all these should be equal to total number of people in the office.
Thus,
a+b+c+d = 38
i.e., 20+(15-d)+(10-d)+d = 38
therefore, 45-d = 38
thus, d= 7
Thus, 7 people like both chocolate drink and cricket.
