In a certain code, SPEND is written as 19-16-5-14-4 and BUDGET is written as 2-21-4-7-5-20, where each letter takes its alphabet position. What is the sum of the numbers in the code for the word TAX?
The sum is 45. Each letter is coded by its alphabet position, so T is 20, A is 1 and X is 24. Adding them gives 20 plus 1 plus 24, which equals 45.
- A45Correct
- B44
- C46
- D54
Explanation
Using alphabet positions, T=20, A=1, X=24. The sum is 20+1+24=45. Option 44 results from treating X as 23, and 46 from treating X as 25.
