In a coding system, if BANK = 2-1-14-11 (where A=1, B=2, C=3, and so on), how would GIFT be coded?
GIFT is coded as 7-9-6-20 because G is the 7th letter, I is the 9th letter, F is the 6th letter, and T is the 20th letter of the alphabet.
- A7-9-6-20Correct
- B7-9-7-20
- C6-9-6-20
- D8-9-6-20
Explanation
Using the coding system where A=1, B=2, C=3... Z=26: G=7, I=9, F=6, T=20. So GIFT = 7-9-6-20. Option 1 incorrectly assigns 7 to F. Option 2 is wrong because it codes I as 9 but F as 7. Option 3 miscodes G as 6. The correct answer follows the alphabetical position rule consistently.
