In a coding system, every letter is replaced by its position in the alphabet (A=1, B=2, C=3, and so on). What is the sum of the codes of the letters in the word CAFE?
The sum is 15. Under the position-value code, C is 3, A is 1, F is 6 and E is 5, and adding these four values gives 15.
- A14
- B15Correct
- C16
- D18
Explanation
C=3, A=1, F=6, E=5. The sum is 3+1+6+5=15. Option 14 comes from using E=4, which is the wrong position for E.
