In a certain code, each letter is replaced by its position in the alphabet (A=1, ..., Z=26) and the result is then multiplied by 2. What is the code for the word BAG?

BAG is coded as 4-2-14. The positions are B=2, A=1 and G=7, and each is multiplied by 2, giving 4, 2 and 14. Writing them in order gives the code 4-2-14.

  1. A4-2-14Correct
  2. B2-1-7
  3. C4-2-12
  4. D3-2-14

Explanation

B=2, A=1, G=7. Doubling gives 4, 2 and 14. Option 2-1-7 skips the doubling; 4-2-12 takes G as 6; 3-2-14 adds 1 to B instead of doubling.
