LCM of a and 18 is 36 and HCF of a and 18 is 2, then a= (a) 2 (b) 3 (c) 4 (d) 1

Show that the points P (-2, 3, 5) , Q (1, 2, 3) and R (7, 0, -1) are collinear.

In Figure, Q R is a common tangent to the given circles touching externally at the point T . The tangent at T meets Q R at P . If P T=3. 8 c m , then the length of Q R (in cm) is (a) 3.8 (b) 7.6 (c) 5.7 (d) 1.9
