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.

Your Performance  

Match the entries in Column I with those in Column II.

Column IColumn II
(A) θ and φ are acute angles such that sin θ = 1/2 and
cos φ = 1/3. Then θ + φ lies in the interval
(p) (−6, −7)
(B)   f (x) = x 2 − 1 and g (x) = sin x + cos x.
Then   f (g (x)) is invertible in the domain
(q) [−π/4, π/4]
(C) Tangent to the parabola y = x 2 + 6 at the point P (1, 7)
touches the circle x 2 + y 2 + 16x + 12y + c = 0 at point Q.
Then the co-ordinates of Q are
(r) (π/2, 2π/3)
(D) The centre of the circle inscribed in the square formed
by the lines x 2 − 8x + 12 = 0 and y 2 − 14y + 45 = 0 is
(s) (4, 7)
