On the edges A1B1 , AB and CC1 of the prism ABCA1B1C1 , the points M , N and P are located , respectively, so that A1M : MB1 = BN : NA = C1P : P C = 1 : 2 . Construct a prism section with a plane (MNP) and find the ratio C1Q : B1C1 , where Q is the intersection point of the plane (MNP) with the straight line B1C1 .
