Worked practice questions

In a certain code, TEAM is written as WHDP. How will COINS be written in the same code?

  1. FRLBZ
  2. FRLQV
  3. RVJQL
  4. QJPTU
Show answer and solution

Correct answer: B. FRLQV

1. Each letter shifts forward by 3: T→W, E→H, A→D, M→P. 2. Apply +3 to COINS: C→F, O→R, I→L, N→Q, S→V. 3. So COINS becomes FRLQV. _Source: RRB Group D CEN-02/2018 PYQ, Q.84._

If in a certain language 'MAT' is coded as KYR, how is 'HIS' written in the same language?

  1. FGT
  2. FGR
  3. FGH
  4. FGQ
Show answer and solution

Correct answer: D. FGQ

1. Each letter shifts back by 2: M→K, A→Y, T→R. 2. Apply −2 to HIS: H→F, I→G, S→Q. 3. So HIS becomes FGQ. _Source: RRB Group D CEN-02/2018 PYQ, Q.95._

If C = 24 and EYE = 46 using reverse alphabetical values (A = 26, B = 25, ...), then FOX = ?

  1. 38
  2. 35
  3. 36
  4. 40
Show answer and solution

Correct answer: C. 36

1. Reverse values: C = 24 (27−3). For EYE: E = 22, Y = 2, E = 22; sum = 46. 2. For FOX: F = 21, O = 12, X = 3. 3. Sum = 21 + 12 + 3 = 36. _Source: RRB Group D CEN-02/2018 PYQ, Q.12._
