1) Company M and N order the same number of computers
2) Company N order 10 computers more than M.


I found this q weird.
For M, C(M) + P(M) = 50
For N, C(N)+ P(N) = 60

A does not say anything about printers for M and N. It can be 10 and 10, 20 and 20, 30 and 30 or any such combi
B same issue as A
On Combining, the info in both options is ambiguous. M and N computers are same where B says N has 10 more than M. How both of them can be true?

It's straight E. Consider the following cases:

#1: M ordered 5 computers and 45 printers, N ordered 5 computers and 55 printers;
#2: M ordered 10 computers and 40 printers, N ordered 10 computers and 50 printers;
