1. Student sold 3 winning tickets.
2.there were 25 prizes in raffle.


Is the question:
how many tickets did student sell?

1.
Sold 3 winning tickets doesn't give us any indication how much he sold.
If
Total=100; He sold=40; 3 won
Total=50; He sold=20; 3 won

Not Sufficient.

2.
25 prizes and we are given that prizes=10%
Thus total=25*10=250
He sold=0.4*250=100
Sufficient.

Ans: "B"

Is the question typed wrong? The question says how many were won but fluke answered how many sold? I answered correctly but I think it was for the wrong reason. The question asked for how many ticket did student win? (Which I thought was odd phrasing).

Edited the question. Below is correct version:
A certain student sold exactly 40% of all the tickets sold for a raffle, and exactly 10% of all ticket-holders won prizes in the raffle. If all ticket-holders purchased only one ticket, and if each ticket could win a maximum of one prize, how many tickets did the student sell?

(1) The student sold 3 winning tickets.
(2) There were 25 available prizes to be won in the raffle.

Are we assuming all prizes were won? If so, how can we assume this?

B states that 25 prizes were available.
