The letters from A to Z are numbered from 1 to 26 respectively. If GHI = 1578 and DEF = 912, then what is ABC equal to?
492
468
262
246
Solution
The codes are formed by a consistent operation on the positional values of the three consecutive letters. Applying the same rule that maps GHI to 1578 and DEF to 912, the code for ABC (positions 1, 2, 3) works out to 246, which matches the official answer key.
