In a queue, Shubham is at seventeenth place from left end and Amar is at the fifteenth place from right end. After interchanging their places, Shubham takes the tenth place from the left end. Which place does Amar take from right end?
Answers
Answer: 8th
Step-by-step explanation:
Shubham is at the seventeenth place from the left end and Amar is at the fifteenth place from the right end.
After interchanging their places, Shubham is at tenth place from the left end. This means that Shubham moved right while Amar moved left.
If Amar's place before interchanging was 15th from the right end and the same place (after interchanging) is 10th from the left end, there are total of 24 students.
14 people right of that place + 9 people left of that place + 1 that place which was occupied by Amar and then Shubham = 24.
Now, Amar takes the place where Shubham was 17th from the left end. This means that there are 16 people left of that place. So, the position of Amar from the right end, after interchanging, is 8th.
