Correct Answer - Option 3 : 14th
The logic follows here is:
Position of K from the left = 5
Position of M from the right = 6
After interchanging their position,
Position of K from the left = 13
So, the total person to the right of K from the 5th place = 13 - 5 = 8.
Now,
Position of M from the right = 6 + 8 = 14.
Hence, "14" is the correct answer.
