A fraternity wants to enroll members of the college rowing team as members. The result of the fraternity's effort to recruit new members from the rowing team exceeds the fraternity's expectation by 20 percent. Assuming that the rowing team admits only males, what is the total number of people on the rowing team?

(1) The goal was to enroll 15 percent of the members of the rowing team.

(2) The number of rowing team members enrolling as new fraternity members was 40.

The OA is C.

I don't have it clear. Please, can ant expert assist me with this DS question? Thanks.

What's the source of the question? The data in the question are not appropriate. Anyways, let's understand this.

Say there are a total number of R number of people on the rowing team.

(1) The goal was to enroll 15 percent of the members of the rowing team.

Goal = 15% of R. Can't get R.

(2) The number of rowing team members enrolling as new fraternity members was 40.

The number of rowing team members enrolling as new fraternity members = 40. Can't get R.

40 = 120% of expectation/goal

(1) and (2) combined:

From (1) and (2), we get that

40 = 120% of 15% of R

R = 222.22. It should have been an integer. Sufficient.

The correct answer: C

Hope this helps!
