    1. C
    2. A
    3. C
    Explanation:-

    A+B+C=13
    C+D+E=13
    E+F+G=13
    G+H+1=13
    A+B+C+D+E+F+G+H+I=45 (Thats sum of all digits)
    So C+E+G=52-45=7
    So C,E,G can be only in (1,2,4)
    Now C+D+E=13
    so C and E will be (1,4) or (2,4)
    D can take (7,8)
    So answer is 4 thats C for question 1.

    So sum of C and E is either 5 or 6.

    Now E+F+G=13
    If E=4,F+G=9
    So G can be (1,3,6,7,8) if C=2
    and G can be (2,3,6,7,8) if C=1

    So sum is maching with C=1,E=4 and G=2 that comes C+E+G=7
    C=2,E=4 and G=1 that comes C+E+G=7
    So answer is 7

    Now C,E,G is fixed.
    so B,H can take any value (3,5,6,9)

    So the answer is 4.

    I applied hit and trial method that can prove disastrous in cat
    (1 3 9 will always form a group as pairing of 9 with any other no is nt possible, also c e g can nt be 9 and 8… )


  3. vinoth Says:

    The answer is,
    e=4;
    c+e+g=7;
    Becoz,
    a+b+c=c+d+e=e+f+g=g+h+i=13;
    9+3+1=1+8+4=4+7+2=2+5+6;
    therefore,e=4;c+e+g=7;
    that’s all.


  4. sumit vashishtha Says:

    we have 7 combinations that’s r
    1. 9+1+3=13
    2. 8+1+4=13
    3. 8+2+3=13
    4. 7+1+5=13
    5. 7+2+4=13
    6. 6+2+5=13
    7. 6+3+4=13
    now we have to make possible 4 combination by which we get
    1,2,5,6 and get the values of a,b,c,d,e,f,g,hand i are9,3,1,8,4,7,2,5 and 6 respectively, now we find e=4.
    also c+g+i=7.
