Seven men namely Ai, Bi, Ci, Di, Ei, and Gi are standing in a line.
i. Gi is between Ai and Ei
ii. Fi and Ai have one man between them 
iii. Ei and Ci have two men between them 
iv. Di is immediate right of Fi
v. Ci and Bi have three men between them Who is second from left?

 Since Gi is between Ai and Ei, let us take Ei to the left of Gi and Ai to the right of Gi.  Fi and Ai have one man between them, means Fi is second to the right of Ai (because Ei is second to the left)  Ei and Ci have two men between them, means Ci is between Ai and Fi.  Di is to the immediate right of Fi and Ci and Bi have three men between them. This implies Bi is to the extreme left. Final arrangement is as shown below: From the above arrangement, it is clear that Ei is second from the left. Hence, the correct answer is (C).
