Let's have another math question. The first person to answer it correctly will receive 0.00001000 BTC.

Bob's father is 3 times as old as Bob. Four years ago he was 4 times older. How old is Bob?

If Bob is 36, then his father is 108. Four years ago his father was 104 and Bob was 32, which is NOT 4 times more. So, the answer is wrong. Still waiting for the correct one!
