Answer / anjum kabir

A + B + C | 9 + 3 + 1 = 13 = 6 + 5 + 2
C + D + E | 1 + 8 + 4 = 13 = 2 + 7 + 4
E + F + G | 4 + 7 + 2 = 13 = 4 + 8 + 1
G + H + I | 2 + 5 + 6 = 13 = 1 + 3 + 9
Value of E = 4

13*4 = 52
1+2+3+....+9 = 45

Then C+D+E must be equal to 7
or they must from 1 , 2 or 4.

1 and 2 for E cannot satisfy as because 1 and 2 cannot
come together in C+D+E
hence 1 and 4 and 2 and 4 should be together.

so you get two solutions and putting them any of the either
way you get E = 4. and everynumber gets satisfied with a
unique value.

Answer / rohit parimal

a+b+c=13 - eq 1

c+d+e=13 - eq 2

e+f+g=13 - eq 3

g+h+i=13 - eq 4

we will add all the equations

a+b+c+c+d+e+e+f+g+g+h+i=52 - eq 5

a+b+c+d+e+f+g+h+i+(c+e+g)=52

as the numbers are from 1 to 9
the addition of nine numners from 1 to 9 is 45.
so
a+b+c+d+e+f+g+h+i=45 -eq 6

Putting the value from eq 6 in eq 5

45+c+e+g=52 - eq 7

c+e+g=7 - eq 8

eq 2 says c+d+e=13

Subtracting eq 8 from eq 2

c+d+e-c-e-g=13-7

d-g=6 - eq 9

when we put value 4 in g then the value of d should be 10.
Objction.
So value of g is 1 or 2.

eq 3 says e+f+g=13

When we put the vaue of g as 1 then f should be 8 and e
should be 4.
When we put the value of g as 2 then f should be 9 and e
should be 2.Objection (because no two alphabets can be
same.)

Answer / salma

c+d+e=13 or e+f+g=13

we can equally substitute the value of these

so...

e=13/3=4.3333333333333333333333333333333

Answer / sachin b. umbarkar

a+b+c=13
c+d+e=13
Thus, a+b+c=c+d+e
a+b=d+e .................(I)

e+f+g=13
g+h+i=13
Thus, g+h+i=e+f+g
h+i=e+g ...............(II)

Now add (I)and(II)
We get ,

a+b+h+i=d+g+2e
Thus,
e=(a+b+h+i-d-g)/2 .........Answer

Answer / kavitha

no unique solution but it can bnythng from 1-9

a=11
b=1
c=1
d=11
e=1
f=1
g=11
h=1
i=1
so at last e can be even 1

Answer / revathy

c=13-a-b
thus 13-a-b+d+e=13
e=a+b-d

This maynot have a unique solution
One such solution is:
if a=1, b=1, d=1
e=1
thus satisfying all the equations

0 Answers   Cisco,


You are driving along in your car on a wild, stormy night, it's raining heavily, when suddenly you pass by a bus stop, and you see three people waiting for a bus: An old lady who looks as if she is about to die. An old friend who once saved your life. The perfect partner you have been dreaming about. Which one would you choose to offer a ride to, knowing very well that there could only be one passenger in your car? This is a moral/ethical dilemma that was once actually used as part of a job application. * You could pick up the old lady, because she is going to die, and thus you should save her first; * or you could take the old friend because he once saved your life, and this would be the perfect chance to ! pay him back. * However, you may never be able to find your perfect mate again.
