Exercise: Letter Coding

Questions for: Position-Value Coding

If 'DREAM' is coded as 46 and 'GLORY' is coded as 82, then how would 'TRAIN' be coded using the same pattern?

A: 67
B: 62
C: 72
D: 57
Answer: A

✅ The coding pattern assigns a numerical value to each letter based on its position in the alphabet (A=1, B=2, ..., Z=26).

The code for a word is derived by summing these position values for all its letters and then adding the total number of letters in that word.

For 'DREAM': D=4, R=18, E=5, A=1, M=13. Sum of position values = 4+18+5+1+13 = 41. Number of letters = 5. Code = 41 + 5 = 46.

For 'GLORY': G=7, L=12, O=15, R=18, Y=25. Sum of position values = 7+12+15+18+25 = 77. Number of letters = 5. Code = 77 + 5 = 82.

Applying this pattern to 'TRAIN': T=20, R=18, A=1, I=9, N=14. Sum of position values = 20+18+1+9+14 = 62. Number of letters = 5. Code = 62 + 5 = 67.

Therefore, 'TRAIN' is coded as 67.

❌ Option B (62) is incorrect because it only represents the sum of the position values without adding the number of letters.

❌ Option C (72) is incorrect as it would imply adding 10 (number of letters multiplied by 2) to the sum of position values (62 + 10 = 72), which does not follow the established pattern.

❌ Option D (57) is incorrect as it would imply subtracting the number of letters from the sum of position values (62 - 5 = 57), which does not follow the established pattern.

If in a certain code, 'CAT' is coded as '27', and 'DOG' is coded as '29', then what is 'BIRD' coded as using the same logic?

A: 33
B: 35
C: 37
D: 41
Answer: C

✅ The logic for this position-value coding is to first assign each letter its alphabetical position (A=1, B=2, ..., Z=26).

For 'CAT': C=3, A=1, T=20. The sum of these values is 3 + 1 + 20 = 24. Since 'CAT' has 3 letters, the code is 24 + 3 = 27.

For 'DOG': D=4, O=15, G=7. The sum of these values is 4 + 15 + 7 = 26. Since 'DOG' has 3 letters, the code is 26 + 3 = 29.

The consistent pattern is: (Sum of the alphabetical position values of all letters) + (Total number of letters in the word).

Applying this to 'BIRD': B=2, I=9, R=18, D=4. The sum of these values is 2 + 9 + 18 + 4 = 33.

'BIRD' has 4 letters. Therefore, the code for 'BIRD' is 33 + 4 = 37.

❌ Option A (33) is incorrect because it only represents the sum of the letter's position values, without adding the number of letters in the word.

❌ Option B (35) is incorrect as it does not follow the established pattern of summing letter position values and then adding the letter count.

❌ Option D (41) is incorrect as it results from an arbitrary calculation not consistent with the given examples.

In a certain code language, if 'APPLE' is coded as 50, then what is the code for 'ORANGE'?

A: 60
B: 55
C: 59
D: 63
Answer: A

✅ The coding rule assigns each letter its alphabetical position value (A=1, B=2, C=3, ..., Z=26) and then sums these values for all letters in the word.

For the word 'APPLE': A(1) + P(16) + P(16) + L(12) + E(5) = 1 + 16 + 16 + 12 + 5 = 50.

Following this same rule for the word 'ORANGE': O(15) + R(18) + A(1) + N(14) + G(7) + E(5) = 15 + 18 + 1 + 14 + 7 + 5 = 60.

❌ Option B (55) would result if a letter like 'E' (value 5) was omitted from the sum for 'ORANGE'.

❌ Option C (59) would result if a letter like 'A' (value 1) was omitted from the sum for 'ORANGE'.

❌ Option D (63) suggests an incorrect calculation or misapplication of letter values.

In a certain code language, if `BAT` is coded as 24, then how will `DOG` be coded?

A: 26
B: 37
C: 41
D: 52
Answer: C

✅ The coding rule is based on the alphabetical position value of each letter (A=1, B=2, ..., Z=26).

For the word `BAT`:

  • B is a consonant with position value 2 (taken as is).
  • A is a vowel with position value 1 (doubled to 1 * 2 = 2).
  • T is a consonant with position value 20 (taken as is).

Adding these values: 2 + 2 + 20 = 24. Thus, the rule is: Vowel position values are doubled, and consonant position values remain unchanged, then sum the results.

Applying this rule to `DOG`:

  • D is a consonant with position value 4 (taken as is).
  • O is a vowel with position value 15 (doubled to 15 * 2 = 30).
  • G is a consonant with position value 7 (taken as is).

Adding these values: 4 + 30 + 7 = 41. Therefore, `DOG` is coded as 41.

❌ Option A (26) is incorrect because it represents the sum of direct position values (4+15+7) without applying the vowel doubling rule.

❌ Option B (37) is incorrect because it applies an incorrect rule (e.g., doubling consonants: (4*2)+15+(7*2) = 8+15+14 = 37).

❌ Option D (52) is incorrect because it represents doubling the position value of every letter ((4*2)+(15*2)+(7*2) = 8+30+14 = 52), not just the vowels.

In a certain code language, if 'CAT' is coded as 27 and 'DOG' is coded as 29, how would 'FOX' be coded?

A: 45
B: 48
C: 51
D: 42
Answer: B

✅ In Position-Value Coding, each letter is assigned its alphabetical position value (A=1, B=2, ..., Z=26).

✅ For 'CAT', the position values are C=3, A=1, T=20, summing to 24. Since 'CAT' is coded as 27, the established pattern is (Sum of values) + 3 (24 + 3 = 27).

✅ This pattern is confirmed with 'DOG': D=4, O=15, G=7, summing to 26; adding 3 gives 29, which matches the given code.

✅ Therefore, the coding rule is to sum the alphabetical position values of the letters and then add 3 to that sum.

✅ Applying this rule to 'FOX': F=6, O=15, X=24. Their sum is 6 + 15 + 24 = 45.

✅ Adding 3 to this sum, 45 + 3 = 48. CAT: 3+1+20 = 24 --> 24+3 = 27 DOG: 4+15+7 = 26 --> 26+3 = 29

❌ Option A (45) is incorrect because it only calculates the sum of the position values (6+15+24) without adding the constant '3' found in the pattern.

❌ Options C (51) and D (42) are incorrect as they do not follow the derived pattern of adding 3 to the sum of position values.
