G=0 & H=5
ans:-a+b+c+d=d+e+f+g......1
d+e+f+g=g+h+i...........2
a+b+c+d=g+h+i..........3
from 1:-a+b+c=e+f+g...........(A)
from2:-d+e+f=h+i.................(B)
=>a+b+c+d-g=17
=>b+c+d-g=17-4=13.....4
also a+b+c=e+f+g
a+b+c=g+h+i-d
a+b+c+d-g=17
solve 1&4
a+b+c+d =17
b+c+d-g=13
............................
a+g =4
...........................
=>g=0
h+i=17
=>d+e+f=17
=>d+a+b+c-g=17
=>d+4+b+c=17
=> b+c+d =13
2b+c+d-h=8
...........................
-b+h =5
...............................
=>b=h-5.......(5)
from (A) &(B):e+f+g=d+e+f
=>g=d
=>d=0
from question g+h+i=17
=>0+h+i=17
=>5+i=17 (from(5))
=>5+i=17
=>i=12
i.e a=4,b=0,c=13,d=0,e+f=17,g=0,h=5 |
