In a row of 54 students facing North, Karma is 12th from the left end. If Namgyal is 21st to the right of Karma, what is Namgyal's position from the right end of the line?

Given:

Total number of students in the row = 54

Karma's position from the left end = 12th

Namgyal is 21st to the right of Karma.

Namgyal's position from the left end = Karma's position from the left end + Position of Namgyal to the right of Karma

Namgyal's position from the left end = 12 + 21

= 33

Now, we need to find Namgyal's position from the right end of the line.

Position from the right end = Total number of students - Position from the left end + 1

Namgyal's position from the right end = 54 - 33 + 1

Namgyal's position from the right end = 21 + 1

= 22

Thus, Namgyal's position from the right end of the line is 22nd.

Hence, the correct answer is "Option 1".
