Explanation
The correct answer is option 2 i.e 84
| Understanding | Application |
|
The positional value of each letter is multiplied by 2. These numbers are added, and then 2 is added to the sum to obtain the final code of the word. N: 14 x 2 = 28 + 2 = 30 COT: (3 x 2) + (15 x 2) + (20 x 2) = (6 + 30 + 40) + 2 = 78 |
Similarly, for PET: (16 x 2) + (5 x 2) + (20 x 2) = (32 + 10 + 40) + 2 = 84 Hence, the correct answer is 84. |
