Question 333348
First consider the point P. We can draw 4 distinct lines through PandS, P and T, P and U , P and V.
Similarly we can draw 4 lines through Q and each of the four points on the second line.
At last we can draw 4 lines through R and each of the four points on the second line.
So altogether we can draw 12 distinct lines
ANOTHER METHOD
Join each of the three points on each of the four points on the second line.
We can draw 3*4 = 12 distinct lines
