So, I'd suggest You learn about both and If nothing is hinted by the Question about which to use then Use Hierarchical But Even after this,If they give answer according to Simultaneous, then think of it as a Bad luck (Will happen with most students in that case). Concepts se GATE Questions hain... GATE Questions se Concepts nhi hain. 0 votes 0 votes Please log in or register to add a comment.
