Say Company M ordered x no. of computers and y no. of printers, and Company N ordered p no. of computers and q no. of printers.
Thus, x + y = 50 and p + q = 60.
We have to get the value of y.
Let's take each statement one by one.
(1) Company M and Company N ordered the same number of computers.
=> x = p. However, this information can't get us the value of y. Insufficient.
(2) Company N ordered 10 more printers than Company M.
q – p = 10. However, this information can't get us the value of y. Insufficient.
(1) and (2) together
x + y = 50, p + q = 60, and x = p, we get q – p = 10, which is the same information that we get from Statement 2. Insufficient.
The correct answer:
E
Hope this helps!
