Solution:
Given, there are 25 boys in a horizontal row and Rahul was shifted by three places towards his right side and he occupies the middle position in the row.
Let's assume Rahul's original position from the left end of the row = x
So, after shifting Rahul by three places towards his right side, his new position from the left end of the row = x + 3
Also, we know that Rahul occupies the middle position in the row.
So, the number of boys to Rahul's right side = the number of boys to Rahul's left side
Hence, the number of boys to Rahul's left side = (25 - 1)/2 = 12
Therefore, Rahul's new position from the left end of the row = 12 + 1 (Rahul) + 12 (boys to Rahul's left side) = 25
So, x + 3 = 25
Therefore, Rahul's original position from the left end of the row = 25 - 3 = 22
Hence, the correct answer is (d) 10th.
