What is the value of m+n

+ x y z
4 1 -5 m
e 7 n 10
f 2 -4 5


Had absolutely no clue on this one

made a grid & attached hope it makes more sense now...

I think there is some problem with the question.

Hi,
x+4=1 =>x=-3
y+4=-5=>y=-9
z+4=m=>z=m-4
e+x=7=>e=7-x=10
e+y=n=>n=10-9=1
e+z=10=>10+z=10=>z=0
As z=m-4, m=4

So, m+n=4+1 = 5

Hi,
x+4=1 =>x=-3
y+4=-5=>y=-9
z+4=m=>z=m-4
e+x=7=>e=7-x=10
e+y=n=>n=10-9=1
e+z=10=>10+z=10=>z=0
As z=m-4, m=4

So, m+n=4+1 = 5

Thanks man..
I knew this was a very simple one but it did nt strike me in real time I guessed and moved on.....

+ x y z
4 1 -5 m
e 7 n 10
f 2 -4 5

x+4=1 -> x=-3 ; y+4 =-5 -> y=-9 ; m=z+4
x+e=7 -> e=10 ; y+e=n ->n=1 ; z+e=10 -> z=0
m+n = z+4 + n = 0+4+1 = 5
IMO 5

Couldn't grasp the question in your first post.
You may want to create the grid in MS paint/ppt/photoshop and upload!

IMO 5.

without the grid its difficult to understand the question
