In a row of 54 people facing north, Geeta sits 19th from the left end. If only 19 people sit between Barun and Geeta, then what is Barun’s position from the right end of the line?

Given: 

In a row of 54 people facing north, Geeta sits 19th from the left end.

If only 19 people sit between Barun and Geeta.

Solution:

Total people = 54

Geeta’s position from left = 19th

People between Barun and Geeta = 19

So the distance between them = 19 + 1 = 20

Possible positions of Barun

Case 1: Barun is to the right of Geeta
Position = 19 + 20 = 39th from left

Convert to position from right:

Right position = 54 − 39 + 1 = 16

Case 2: Barun is to the left of Geeta
Position = 19 − 20 = −1 (not possible)

Only valid position:

Barun = 39th from left = 16th from right

So, 16th is Barun’s position from the right end of the line.

Thus, correct option is (a).
