I am just not able to crack this one

. Can someone help me solve this?

1-5+m = 4, so m= 8.
f = 2-4+5 = 3
n = ?
e =?

The correct answer is 5.

Thanks a bunch.

Here you go...

Straight from the table:
m=z+4
n=e+y
---------------------(Adding the above 2 eqns)
m+n=z+e+4+y

Straight from the table:
z+e=10

Now all you need is value of y.
From the table: y+4 = -5. So y = -9

m+n = 10+4+(-9)
= 5
