66. If NO is coded as 210, NOT is coded as 4200 and NOTE is coded as 21000, then how is NOTES coded?

1. A. 399000
2. B. 420000
3. C. 440000
4. D. 630000

Answer: A

Explanation

Let’s analyze the pattern using the alphabetical position of letters (A=1, B=2, …, Z=26).
* N = 14, O = 15
NO = 14 × 15 = 210. This matches the given code.
* N = 14, O = 15, T = 20
NOT = 14 × 15 × 20 = 210 × 20 = 4200. This matches the given code.
* N = 14, O = 15, T = 20, E = 5
NOTE = 14 × 15 × 20 × 5 = 4200 × 5 = 21000. This matches the given code.

The pattern is to multiply the alphabetical positions of the letters in the word.
Now, apply this to NOTES:
N = 14, O = 15, T = 20, E = 5, S = 19
NOTES = 14 × 15 × 20 × 5 × 19
We already calculated NOTE = 21000.
So, NOTES = 21000 × 19 = 399000.
This question tests pattern recognition in coding-decoding, a standard reasoning aptitude.
