Let
Pm = Printers ordered by M
Cm = computers ordered by M
Pn = printeres ordered by N
Cn = computeres ordered by N
From the question
Pm + Cm = 50
Pn + Cn = 60
Target question: Value of Cm
Statement 1 :
Cm = Cn
This does not give an exact value.. Cm = Cn = 10, 20 ,30 etc.
Insufficient
Statement 2
Pn = Pm + 10
Again Pm could take different values and still satisfy the 2 equations
Example:
Pm = 10; Pn = 20 ==> Cm = 40
Pm = 20; Pn = 30 ==> Cm = 30
Taking Statements 1 and 2 Together
Pm + Cm = 50 transforms to
(Pn + 10) + Cn = 50
Pn + Cn = 40
but statement 2 => Pn + Cn = 60
There cannot be any solution to the above equation.
Hence both statements are insufficient.
Answer should be E
