N, n+1, n+2
(n+1)(n+2)=6(n+n+1)-12
n^2+3n+2=12n+6-12
n^2+3n+2=12n-6
n^2-9n+8=0
n^2-n-8n+8=0
n(n-1)-8(n-1)=0
(n-8)(n-1)=0
So there are actually two solutions that satisfy the conditions for the cousin's ages...
1,2, and 3 years old and 8,9,and 10 years old.
check...
2*3=6(1+2)-12, 6=18-12, 6=6
9*10=6(8+9)-12, 90=102-12, 12=12
Answer: 36
Step-by-step: 6 2/3 + 5 1/3 = 12
12 x 3 = 36
