Going by someone's earlier equation : Given every one receives same no. of pens/pencils/pads: n(x+y+z) Stmt 1: x:y:z=2a:3a:4a => equation above becomes =n*9a -cant find n, neither do we know a- insufficient Stmt 2: x+y+z=81, above equations is =n*(81) - insufficient Both : n*81=n*9a =>a=9 , so the equation becomes 9n, still cant find n . Ans E
