## IIT JEE 2007 Practice : MATHEMATICS - Matching Questions

Each question contains 4 entries in Column I namely A, B, C and D which are to be matched with all the correct entries in Column II namely p, q, r and s. One entry in Column I may match with one or more than one entry in Column II. You will be awarded 6 marks if all the 4 entries in column I have been correctly and completely matched. You will be awarded 0 marks in all other cases.
For example, if the correct matching is :     (A) to (q),   (B) to (p) (s),   (C) to (r),   (D) to (p) (r) (s)
then simply type in the input box :               q,ps,r,prs
Your input should not contain any blank spaces; the matching entries for (A),(B),(C) and (D) should be lower case letters in alphabetical order separated only by commas.
