Five people are standing in a row, as shown below. Who is second from the right?

Concept: In a single-row arrangement, a position counted ‘from the right’ starts at the rightmost person as position 1 and increases by one moving leftward — the reverse of counting ‘from the left’, where the leftmost person is position 1. For a row of n people: position-from-right = n − position-from-left + 1.

Application: Apply this to the row, listed left to right as shown: Bindu, Seema, Rani, Reeta, Mary.

1. Start at the right end of the row: Mary is 1st from the right.

2. Move one place left: Reeta is 2nd from the right.

3. Continue moving left: Rani is 3rd from the right.

4. Continue: Seema is 4th from the right.

5. Bindu, at the left end, is 5th from the right.

Cross-check: Cross-check by counting from the left instead: Bindu (1st), Seema (2nd), Rani (3rd), Reeta (4th), Mary (5th). Using position-from-right = 5 − position-from-left + 1, Reeta's position-from-right = 5 − 4 + 1 = 2, which matches the direct count.

So, Reeta is second from the right.
