From the table
d+z=m
e+y=n
We need to find m+n = d+z+e+y
Statement 1
-----------
d+y = -3 not sufficient since we dont have the values
of z and e
Statement 2
-----------
e+z = 12 not sufficient since we dont have the values of d and y
Combing 1 and 2,
we can find m+n
Hence C
d+z=m
e+y=n
We need to find m+n = d+z+e+y
Statement 1
-----------
d+y = -3 not sufficient since we dont have the values
of z and e
Statement 2
-----------
e+z = 12 not sufficient since we dont have the values of d and y
Combing 1 and 2,
we can find m+n
Hence C
