24 May 2012: PYRAMID

Another new number puzzle, it’s usually designed in the form of a pyramid with the participant having to place numerical values into boxes, but has been slightly amended for the blog.

F=A+B   G=B+C   H=C+D   I=D+E   J=F+G   K=G+H   L=H+I   M=J+K   N=K+L  and  P=M+N.

If A=10 H=29 K=47 L=54 and M=76, what is the value of E?

    E = 9

    That was hard, had to draw it out like a pyramid to make progress but even then took about 30 mins to solve. Interesting though

      E is not 9 I’m afraid. Why not write each equation on a different line? Should take you about 5 minutes that way!

    I solved for E, I get E as 13. Now waiting for Paul to give his verdict ;) now if the answer is correct, please be noted that I have taken 8 mins so far :))

  3. E = 13 Because…

    A=10
    B=1
    C=17
    D=12
    E=13
    F=11
    G=18
    H=29
    I=25
    J=29
    K=47
    L=54
    M=76
    N=101
    P=177
