Correct Answer: 83
Solution :
Given:
EACH is written as 97, and EASY is written as 64.
Add 6 to the sum of the position values of the opposite letter pairs of the word EACH to get the required code –
| LETTERS | E | A | C | H |
| OPPOSITE LETTER PAIRS | V | Z | X | S |
| POSITION VALUE | 22 | 26 | 24 | 19 |
(22 + 26 + 24 + 19) + 6 = 97
Thus, EACH is coded as 97.
And, EASY is written as 64 –
| LETTERS | E | A | S | Y |
| OPPOSITE LETTER PAIRS | V | Z | H | B |
| POSITION VALUE | 22 | 26 | 8 | 2 |
(22 + 26 + 8 + 2) + 6 = 64
Thus, EASY is coded as 64.
Similarly, follow the same pattern for ECHO –
| LETTERS | E | C | H | O |
| OPPOSITE LETTER PAIRS | V | X | S | L |
| POSITION VALUE | 22 | 24 | 19 | 12 |
(22 + 24 + 19 + 12) + 6 = 83
Thus, ECHO is coded as 83. Hence, the third option is correct.
