Directions: Study the following information carefully and answer the questions given below: In a hexagon arrangement, at each corner, a triangle is placed which is denoted by either two letters or two numbers. Below are given some of the conditions: 

I. If the number is a perfect square then only that number is increased by 1.

II. If there is at least one vowel then change it to the preceding alphabet.

III. If both digits are odd then reduce those digits by 2.

IV. If any one of the consonants is smaller than N in alphabetical order then change it to the next alphabet.

Note: If no condition is applied then there will be no change. Apply the above-given conditions to find the output. More than one condition can be applicable. For example:
