As you are looking for WBJEE math’s paper solutions key of last year so on your demand I am providing same here :

1. Transforming to parallel axes through a point (p, q), the equation
2x2 + 3xy + 4y2 + x + 18y + 25 = 0 becomes 2x2 + 3xy + 4y2 = 1. Then
(A) p = 2, q = 3 (B) p = 2, q = 3 (C) p = 3, q = 4 (D) p = 4, q = 3
Solution : (B)
2. Let A(2, 3) and B( 2, 1) be two angular points of  ABC. If the centroid of the triangle moves on the
line 2x + 3y = 1, then the locus of the angular point C is given by
(A) 2x + 3y = 9 (B) 2x 3y = 9 (C) 3x + 2y = 5 (D) 3x 2y = 3
Solution : (A)
3. The point P(3, 6) is first reflected on the line y = x and then the image point Q is again reflected on the
line y = x to get the image point Q. Then the circumecentre of the PQQ is
(A) (6, 3) (B) (6, 3) (C) (3, 6) (D) (0, 0)
Solution : (D)
4. Let d1 and d2 be the lengths of the perpendiculars drawn from any point of the line 7x 9y + 10 = 0 upon
the lines 3x + 4y = 5 and 12x + 5y = 7 respectively. Then
(A) d1 > d2 (B) d1 = d2 (C) d1 < d2 (D) d1 = 2d2
Solution : (B)
5. The common chord of the circles x2 + y2 4x 4y = 0 and 2x2 + 2y2 = 32 subtends at the origin an angle
equal to
(A) 3


(B) 4
 (C) 6


(D) 2


Solution : (D)
6. The locus of the mid-points of the chords of the circle x2 + y2 + 2x 2y 2 = 0 which make an angle
of 90o at the centre is
(A) x2 + y2 2x 2y = 0 (B) x2 + y2 2x + 2y = 0
(C) x2 + y2 + 2x 2y = 0 (D) x2 + y2 + 2x 2y 1 = 0
Solution : (C)
