If MYSTIFY is coded as NZTUJGZ, how is letter A coded in this rule?

  1. B
  2. Z only
  3. Y only
  4. A only
Show answer and solution

Correct answer: A. B

1. The chapter Case 1 explains: each letter +1. 2. M to N, Y to Z, S to T, T to U etc. 3. So A -> B by the same +1 shift. 4. Hence option A. _Source: jkchrome.com SSC Coding-Decoding PDF (Mistral OCR), Case 1, Letter Coding_

In a code, CAT = 3-1-20 (position numbers). What is the code for DOG?

  1. 3-15-7 only
  2. 4-15-7
  3. 4-14-8 only
  4. 5-15-7 only
Show answer and solution

Correct answer: B. 4-15-7

1. Number coding: replace each letter by its position in A-Z. 2. D=4, O=15, G=7. 3. So DOG = 4-15-7. 4. Hence option A. _Source: jkchrome.com SSC Coding-Decoding PDF (Mistral OCR), Type 2 Number Coding_
