[quote]the answer for the puzzle is

2+5+3=132
3+6+4=380
4+2+7=63
6+3+6=228
8+5+2=?
rule is
a+b+c = p*q where p=(a*b)+1 and q=(b*c)-c
following the above we have
for 8+5+2, p=(8*5)+1=41 and q=(5*2)-2=8 ; p*q=41*8=328

8+5+2=328[/quote]


That was really typical to solve, I could never get it. Please try to post some easy ones, so that it could be answerable.
