Step-by-Step Logical Deduction

To solve this puzzle, we can use a process of elimination by applying each clue sequentially to determine the shirt and pant color for each person (A, B, and C).

The available colors are:

• Shirts: Black, Blue, Orange
• Pants: Green, Yellow, Orange

A key rule is that no person wears a shirt and pant of the same color.

Step 1: Determine B's outfit

• Clue 6: "B wore pant of orange colour." We know B's pant is Orange.
• Since B's pant is Orange, his shirt cannot be Orange (due to the main rule).
• Clue 3: "B did not wear shirt of blue colour."
• Since B's shirt is not Orange and not Blue, it must be the only remaining color: Black.

Result for B: Shirt - Black, Pant - Orange.

Step 2: Determine C's outfit

• The shirts worn so far are Black (by B). The remaining shirt colors are Blue and Orange.
• Clue 4: "C did not wear shirt of orange colour."
• Therefore, C must wear the only other available shirt color: Blue.
• The pants worn so far are Orange (by B). The remaining pant colors are Green and Yellow. We will determine C's pants in the next step.

Result for C (so far): Shirt - Blue.

Step 3: Determine A's outfit and C's pants

• The only remaining shirt color is Orange, which must be worn by A.
• The remaining pant colors are Green and Yellow. One is for A, the other for C.
• Clue 5: "A did not wear pant of green colour."
• Therefore, A must wear the only other available pant color: Yellow.
• This leaves the last remaining pant color, Green, for C.

Result for C (final): Shirt - Blue, Pant - Green.

Conclusion

The question asks for the colors of the pant and shirt worn by C, respectively. Based on our deductions, C wore a Green pant and a Blue shirt.
