Answer: Option E
Explanation:
From II, we conclude that in a class of 40,
Deepak ranks 23rd from the bottom i.e. 18th from the top.
From I and II, we find that Suman is 3 ranks
below 18th rank from the top i.e. she ranks 21st from the top.
From II and III, we find that Suman is 3
ranks above 23rd rank from the bottom
i.e. she ranks 20th from the bottom or 21st
from the top.
