If it is a 3x3 matrix, for which elements
in first row are (V, 50, W), second row (196,
X, Y)and in third row are (269, Z, 123).It is
given that the sum of the numbers in each
row, column, diagonal are same. Then find
the value of (Y + Z).

- Ans : 1122
matrix
v 50 w
196 x y
269 z 123
in 1st row and 1st column
v+196+269=v+50+w
w=415
Again, in 2nd column and 3rd row
50+x+z=269+z+123
x=342
As sum of each row column and diagonal are same.
So, 269+342+415=1026
415+y+123=1026
y=488
269+z+123=1026
z=634
y+z=488+634=1122 - 9 years agoHelpfull: Yes(31) No(1)
- v 50 w
196 x y
269 z 123
v+50+w=v+196+269
w=196+269-50
w=465-50=415
similarly
v+x+123=w+x+269
v=415+269-123
v=561
and
so on

- ans-1122
matrix is
v 50 w
196 x y
269 z 123
then we make a equation x+50+z=269+z+123,
then we get x=342,
same as we get w=415,
from v+342+123=50+v+w,
then we get total of a diagonal 269+x+w=1026,
then we get y=488,from equation w+y+123=1026,
and get z =634,from 269+123+z=1026, - 9 years agoHelpfull: Yes(0) No(0)
- v 50 w
196 x y
269 z 123
this is the matrix assume sum is s
by solving v+196+269=s and v+x+123=s
we get x=342
by solving w+y+123=s and w+322+269=s
we get y=468
then cal. sum and cal. z=614
and the ans is y+z is 1082 - 9 years agoHelpfull: Yes(0) No(0)
