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.
We need to know the # of members of the rowing team.
(1) The goal was to enroll 15 percent of the members of the rowing team.We cannot tell anything about the # of members of the rowing team. We can only tell that more than this # was enrolled.
INSUFF.(2) The number of rowing team members enrolling as new fraternity members was 40This is \(20\% \) more than intended. Hence intended number was \(80\%\) of \(40 = 32\)
Hence we know the intended number for enrollement. Still we cannot tell about the # of members of the rowing team.
INSUFF.1+2
From (2) we know intended # is \(32\) and from (1) we know that \(32\) is \(15\%\) of the members of the rowing team.
so if \(x\) is the # of members of the rowing team , we can write \(15 \%\) of \(x = 32\)
\(.15*x=32\)
\(x= \frac{3200}{15}\)
SUFF.

Hope it's clear.
(P.S.- Unless I have messed up somewhere, # of members should have come out as an integer.)
