Answer: 6.
The idea
The most basic letter-value code. Larger words use the same idea, so speed at converting letters to numbers pays off.
Shortcut. CAB uses each of the first three letters once, so the value is 1 + 2 + 3 = 6 whatever the order of the letters.
Common trap. "5" — valuing A at 0, as zero-based indexing would, which gives 3 + 0 + 2 = 5; the question fixes A = 1.
