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

• 7puzzle says:

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

• awizzbang says:

E = 11

Hopefully correct this time, I think I just made it too complicated, great puzzle, especially if I got it correct this time

• 7puzzle says:

Thanks Martin, but not correct. Vijay is I’m afraid.

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 :))

Cheers
Vijay

The answer is . . . . . 13, yay!!

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
