m + n = (z+4) + (y+e) = (z+e) + (y+4) = 10 + (-5) = 5

Hence C

Hi Chintudave,


Not sure how did you got that formula. Is they any theory available for this or I missed something?

Thanks

The Table represents 9 equations
x+4=1
x+e=7
x+f=2

y+4=-5
y+e=n
y+f=-4

z+4=m
z+e=10
z+f=5

so m+n = y+e+z+4 ; y+4 = -5 and z+e = 10; 10-5 = 5

M=4+Z = 4+10-E = 14-E ------------------(1)
N=E+Y = E-9 ---------------------(2)

ADD 1 AND 2

M+N = 14-E+E-9 = 5 ANS. C
