i go with Csuperrrom wrote:Thanks, answer is C
n divided by 25 leaves remainder 13.
Statement 1 , n<100
hence n can be 13, 38, 63, 88.. insufficient
Statement 2. n when divided by 20 leaves remainder 3.
can be 3, 23, 43,63,83,103,123,143,163...............
both 63 and 163 when divided 25 leaves remainder 13.
hence insufficient
taking both ..we know n=63
hence c.
Hope that helps..
