Alice is ranked 15th from the bottom in a group of 40 people. If she swaps ranks with Bob, who is ranked 10th from the top, what will be Alice's new rank from the top?
Answer: C. 25th
If Alice is 15th from the bottom in a group of 40, she is 40 - 15 + 1 = 26th from the top. After swapping with Bob, who is 10th from the top, Alice's new rank from the top becomes 10th.
