• A. Any two of the three
• B. Only I and II
• C. Only II and III
• D. All I, II and III
• E. Only II and either I or III

Answer 1

The correct option is E Only II and either I or III

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.
