The previous year question paper of Chhattisgarh Pre-Engineering Test (CG P.E.T) is as follows:

For two circles, if the distance between their centres is equal to the sum of their radii, then the number of common tangents exist for the system, are:
(A) 2
(C) 4
(8) 3
(D) No common tangent exist


If Y= x + a is tangent to the parabola y2 = 4(x + 1), then the value of a, is:
(A) 1 (8) 4
(C) .....1 (D) 2


The locusofthe middle points of those chords of the circle x2+ 1= 16 which subtend aright angle at the origin is:
(A) x2- 1=0
(8) x2+ 1=8
(CP)2x2+ 1=4
(0) x2+ 1=4

Centre of the conic16x2 + 251 - 32x - 1OOy- 284 = 0 is:
(A) (1,2)" (6) (2, 1)
(C) (-1,~) (0) (1,-2)

The co-ordinates of a point in the x~ plane which is equidistant from the three points
A, 8 and C whose position vectors are i, j and k, is:
(A) (1, 1,0)
(8) (0, 0,,0)
(C) (0,1,0)
(0) (1',-1,0)
