1. Calculate the value for each envelope:
- L: 2 x 8 = 16
- Y: 4 x 9 = 36
- ER: 6 x 4 = 24
- L: 3 x 9 = 27
- C: 4 x 6 = 24
- N: 6 x 3 = 18
- E: 5 x 5 = 25
- S: 3 x 4 = 12
2. Arrange the letters in ascending order of their calculated values:
- S (12)
- L (16)
- N (18)
- ER (24) and C (24) — both have same value, so order them alphabetically by letter: C then ER
- E (25)
- L (27)
- Y (36)
3. The sequence of letters is: S, L, N, C, ER, E, L, Y
4. Combine the letters to form the word: S L N C E R E L Y
5. Rearrange the letters to find a meaningful word that answers the question “What word do you use to end a letter?”
- The correct arrangement is: S I N C E R E L Y
6. Final answer: SINCERELY
