If the words FAST, SLOW and TONE are written as 3475, 2913 and 1648 but not necessarily in the same order, then using the same code how the word NEAT would be written?

Correct option is C

Solution:

Each word has four letters mapped to a four-digit code, with each letter assigned a unique digit. The unique letters (F, A, S, T, L, O, W, N, E) correspond to digits (1, 2, 3, 4, 5, 6, 7, 8, 9).

Find the Mapping:
Test assignments for consistency across shared letters (S in FAST, SLOW; T in FAST, TONE; O in SLOW, TONE).

Correct Mapping (from consistent deduction):

• TONE = 3475=> T = 3, O = 4, N = 7, E = 5
• SLOW = 1648=> S = 1, L = 6, O = 4, W = 8
• FAST = 2913=> F = 2, A = 9, S = 1, T = 3

No digit is used more than once, and all mappings are consistent.

For NEAT:

• N = 7
• E = 5
• A = 9
• T = 3

=>NEAT = 7593

Correct Answer: (C) 7593
