BPSC – Combined Competitive Examination · Question 2

SPRING is written in a code as UNUFRC. How will the word MOBILE be written in that code language?

  1. OMEFPA
  2. OMPGNC
  3. MPQSUL
  4. SEGRFT
Show answer & explanation

Answer: (A) OMEFPA

Explanation

S(+2)=U, P(−2)=N, R(+3)=U, I(−3)=F, N(+4)=R, G(−4)=C. Applying the same shifts to MOBILE gives OMEFPA.

  • (A) Correct

    Correct: the pattern is +2, −2, +3, −3, +4, −4: M→O, O→M, B→E, I→F, L→P, E→A.

  • (B) Incorrect

    Wrong: only the first two letters fit; B+3 gives E, not P.

  • (C) Incorrect

    Wrong: M should shift +2 to O, so the code cannot start with M.

  • (D) Incorrect

    Wrong: does not follow the +2, −2, +3, −3, +4, −4 pattern at all.
