If ROSE is coded as 6821, CHAIR is coded as 73456 and PREACH is coded...
To find the code for the word SEARCH, we need to analyze the given codes for the words ROSE, CHAIR, and PREACH.
1. Analyzing the code for ROSE:
- The word ROSE is coded as 6821.
- We can observe that the code for each letter is obtained by subtracting the position of the letter in the English alphabet from 9.
- For example, R is in the 18th position in the alphabet, so its code is 9 - 18 = -9 (which is equivalent to 9 since we are taking only positive values).
- Similarly, the code for O is 9 - 15 = -6 (which is equivalent to 6), S is 9 - 19 = -10 (which is equivalent to 10), and E is 9 - 5 = 4.
2. Analyzing the code for CHAIR:
- The word CHAIR is coded as 73456.
- Again, the code for each letter is obtained by subtracting the position of the letter in the English alphabet from 9.
- For example, C is in the 3rd position in the alphabet, so its code is 9 - 3 = 6.
- Similarly, the code for H is 9 - 8 = 1, A is 9 - 1 = 8, I is 9 - 9 = 0, and R is 9 - 18 = -9 (which is equivalent to 9).
3. Analyzing the code for PREACH:
- The word PREACH is coded as 961473.
- Once again, the code for each letter is obtained by subtracting the position of the letter in the English alphabet from 9.
- For example, P is in the 16th position in the alphabet, so its code is 9 - 16 = -7 (which is equivalent to 7).
- Similarly, the code for R is 9 - 18 = -9 (which is equivalent to 9), E is 9 - 5 = 4, A is 9 - 1 = 8, C is 9 - 3 = 6, and H is 9 - 8 = 1.
4. Finding the code for SEARCH:
- Using the same logic as above, we find that S is in the 19th position in the alphabet, so its code is 9 - 19 = -10 (which is equivalent to 10).
- Similarly, the code for E is 9 - 5 = 4, A is 9 - 1 = 8, R is 9 - 18 = -9 (which is equivalent to 9), C is 9 - 3 = 6, and H is 9 - 8 = 1.
- Therefore, the code for SEARCH is 1048961, which corresponds to option D.
In conclusion, the code for the word SEARCH is 214673 (option D).
If ROSE is coded as 6821, CHAIR is coded as 73456 and PREACH is coded...
ROSE = 6 8 2 1
CHAIR = 7 3 4 5 6
PREACH = 9 6 1 4 7 3
There is exactly one digit for one letter.
So, code for SEARCH = 2 1 4 6 7 3
