In a class of 25 students, Shivani is 7th from top and Reema is 16th from bottom. The rank of Ashwini is the same from both sides. Reema and Ashwini interchange their ranks and later Ashwini interchanges her new rank with Shivani.
What is Ashwini's rank from the bottom?
16th
18th
17th
19th
Since Ashwini's rank is the same from both ends, Ashwini is ranked 13th.
Since Reema is ranked 16th from the bottom, she is ranked (25 – 16 + 1)th i.e. 10th from the top.
Since Reema and Ashwini interchange their positions, now Reema is ranked 13th from the top and Ashwini is ranked 10th from the top.
Now, Ashwini interchanges her new rank with Shivani.
Hence, Shivani is ranked 10th from top and Ashwini is ranked 7th from top.
Hence, Ashwini's rank from bottom = 25 + 1-7 - 19th from the bottom.
Hence, option d.
