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

Correct Answer: c) OMEFPA

Explanation:
Observe the pattern from SPRING → UNUFRC by using alphabet positions (A=1, B=2, …, Z=26):
– S(19) → U(21): +2
– P(16) → N(14): −2
– R(18) → U(21): +3
– I(9) → F(6): −3
– N(14) → R(18): +4
– G(7) → C(3): −4

So the rule is: alternately add and subtract, increasing the step each time: +2, −2, +3, −3, +4, −4.

Apply the same to MOBILE:
– M(13) +2 → O(15)
– O(15) −2 → M(13)
– B(2) +3 → E(5)
– I(9) −3 → F(6)
– L(12) +4 → P(16)
– E(5) −4 → A(1)

Thus, MOBILE → OMEFPA.
