Re: wb jee old question papers
The previous year Mathematics question paper for preparation of West Bengal Joint Entrance Exam (WBJEE) is as follows: The points (–a, –b), (a, b), (0, 0) and (a2, ab), a 0, b 0 are always lie on this line. Hence, collinear (A) collinear (B) vertices of a parallelogram (C) vertices of a rectangle (D) lie on a circle Ans : (A) x + 8y – 22 = 0, 5x + 2y – 34 = 0, 2x – 3y + 13 = 0 are the three sides of a triangle. The area of the triangle is (A) 36 square unit (B) 19 square unit (C) 42 square unit (D) 72 square unit Ans : (B) The line through the points (a, b) and (–a, –b) passes through the point (A) (1, 1) (B) (3a, –2b) (C) (a2, ab) (D) (a, b) Ans : (C) The equation of a line parallel to the line 3x + 4y = 0 and touching the circle x2 + y2 = 9 in the first quadrant is (A) 3x + 4y = 15 (B) 3x + 4y = 45 (C) 3x + 4y = 9 (D) 3x + 4y = 27 Ans : (A) A straight line joining the points (1,1,1) and (0,0,0) intersects the plane 2x+2y+z=10 at (A) (1, 2, 5) (B) (2, 2, 2) (C) (2, 1, 5) (D) (1, 1, 6) Ans : (B) |
