SSC CGL 26 Oct 2014 Shift 2 Paper

The pattern is an alternating alphabet shift: the 1st and 3rd letters move $4$ places backward, while the 2nd and 4th letters move $4$ places forward.For $YAWC$ : $UESG$: $Y$ becomes $U$, $A$ becomes $E$, $W$ becomes $S$, and $C$ becomes $G$.Apply the same rule to $QIOK$:$Q$ moves $4$ places backward to $M$.$I$ moves $4$ places forward to $M$.$O$ moves $4$ places backward to $K$.$K$ moves $4$ places forward to $O$.So $QIOK$ : $MMKO$.Therefore, the correct option is $MMKO$.
