In a row of people, Rathna is 16th from the left end. Rathna is ninth to the left of Amrinder who is fourth to the right of Mahendran who is 24th from the right end. Then, how many people are there in the row?
(a) 43
(b) 42
(c) 20
(d) 44
Answer (1)
To solve the problem of determining the number of people in the row, we follow a step-by-step approach:
Identify the Positions of Rathna and Mahendran:
Rathna is 16th from the left end.
Mahendran is 24th from the right end.
Determine the Position of Amrinder Relative to Rathna and Mahendran:
Rathna is ninth to the left of Amrinder.
This means if Rathna is at position 16, Amrinder is 16 + 9 = 25th from the left.
Amrinder is fourth to the right of Mahendran.
So, if Amrinder is at position 25 from the left, and he is fourth to the right of Mahendran, then Mahendran is at position 25 - 4 = 21st from the left.
Calculate the Number of People in the Row:
We know Mahendran's position is 24th from the right and 21st from the left. If we add these positions and subtract 1 (since Mahendran is counted twice), we get the total number of people in the row.
Total number of people = 21 + 24 − 1 = 44
Thus, the number of people in the row is 44 .
Therefore, the correct multiple-choice answer is (d) 44.
