Question

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

Options

a

399000

Answer
b

420000

c

440000

d

630000

Explanation

Convert the letters to their standard alphabetical positions: N=14, O=15, T=20, E=5, S=19. Test mathematical operations. Multiplication is the most likely candidate for such rapidly escalating values: NO = 14 × 15 = 210. NOT = 14 × 15 × 20 = 4200. NOTE = 4200 × 5 = 21000. The coding logic is the continuous product of the alphabetical positional values. To find NOTES, multiply the value of NOTE by the position of S (19): NOTES = 21000 × 19 = 399000.

When word codes escalate exponentially from 2-letter to 4-letter words, immediately test the product of their alphabetical rank values.

Answer: (a).
