The strip shows the last ten 3-digit numbers. What is the LARGEST 3-digit number that is divisible by 12?

Divisible by 12 means divisible by 3 and by 4. 999 is divisible by 3 but odd; 992 passes the 4-test (92) but $9+9+2=20$ fails the 3-test. 996: last two digits 96 are divisible by 4, and $9+9+6=24$. So 996 $=12\times 83$.
