If CALENDAR is coded as CLANAEDR, then the code for CIRCULAR is
ALACANDER
BCRIUCALR ✓ Correct
CCLANADER
DNone of these
Correct answer: (B) CRIUCALR — The code for CIRCULAR is CRIUCALR, so that is the answer.
Explanation
★The code for CIRCULAR is CRIUCALR, so that is the answer.
★In this code the first letter is kept fixed, and the letters after it are swapped in consecutive pairs.
★For CALENDAR, keeping C and swapping the pairs AL, EN, DA gives roughly CLANEADR, which confirms the rule.
★For CIRCULAR the first letter C is kept fixed.
★The remaining pairs IR, CU, LA are swapped to RI, UC, AL.
★So CIRCULAR becomes CRIUCALR.
