Question
In a row of boys, Amit and Sumit are 12th and 16th from right and left end respectively. If both of them interchange their positions then Amit becomes 25th from the right end. What will be the new position of Sumit from the left end?a.29thb.24thc.30thd.27th
Solution
The problem can be solved in the following steps:
Step 1: We know that Amit is 12th from the right and after interchanging positions with Sumit, he becomes 25th from the right.
Step 2: This means that Sumit is now in the position that was originally 12th from the right.
Step 3: We also know that Sumit was originally 16th from the left.
Step 4: Since the positions have been interchanged, the new position of Sumit from the left end will be the sum of his original position from the left and the difference in Amit's positions from the right before and after the interchange.
Step 5: The difference in Amit's positions from the right before and after the interchange is 25 - 12 = 13.
Step 6: Adding this difference to Sumit's original position from the left gives us 16 + 13 = 29.
So, the new position of Sumit from the left end is 29th. Therefore, the answer is a. 29th.
