C
Q stem gives n(ax+by+cz)
A gives n(2x+3y+4z)
B gives 18x+27y+36z

Compare with q stem you will get the answer.

Pens: 18 = 2 x 3 x 3
Pencils: 27 = 3 x 3 x 3
Pads: 36 = 4 x 3 x 3
Then, number of staff members: 3 or 3x3=9

I don't understand whether the answer is C or E. If it is C, then it is a straightforward question. If it is E, Could someone elaborate..

To know the number of people, simply knowing the ratio of division is not enough. Both the statements only provide the ratio of distribution.

combine them and check, the ratio will remain 2:3:4

either there can be 3 people, each getting 6, 9 and 12
or there can be 9 people, each getting 2, 3, and 4

in both cases, both statements 1 and 2 are being satisfied. You don't get a unique answer.

Going by someone's earlier equation :
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
