Q 21 / 325

UPSC CSE Prelims 2025

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

EXPLANATION

Correct Option (1)

The coding pattern involves multiplying the alphabetical position of each letter in the given word.

  • For NO: N is the 14th letter, O is the 15th letter. Code = 14 × 15 = 210.
  • For NOT: N (14), O (15), T (20). Code = 14 × 15 × 20 = 4200.
  • For NOTE: N (14), O (15), T (20), E (5). Code = 14 × 15 × 20 × 5 = 21000.

Applying this pattern to NOTES:

  • N = 14
  • O = 15
  • T = 20
  • E = 5
  • S = 19

Therefore, NOTES = 14 × 15 × 20 × 5 × 19 = 399000.

Incorrect Options:

Options 2, 3, and 4 are incorrect as they do not conform to the established logical pattern of multiplying the alphabetical positions of the letters to derive the coded value.
