Explanation

To solve this, we first look at the alphabetical positions of each letter: N = 14, O = 15, T = 20, E = 5, and S = 19. The coding logic is the product of these alphabetical positions. For NO: 14 multiplied by 15 equals 210. For NOT: 14 multiplied by 15 multiplied by 20 equals 4200. For NOTE: 14 multiplied by 15 multiplied by 20 multiplied by 5 equals 21000. Following this pattern for NOTES, we multiply the value of NOTE by the position of S: 21000 multiplied by 19 equals 399000. Therefore, the correct option is A.
Logical Reasoning: If NO is coded as 210, NOT is coded as 4200 and NOTE is coded as 21000, then how is NOTES coded?
