Feel free to solve ..

There are three different sets of parallel lines. 5 in the first set, 6 in the second and 4 in the third.
If no three lines intersect at one point, then how many triangles are formed? No two lines in any two different sets are parallel to each other.
a) 60
b) 120
c) 30
d) none of these

    The answer is 4 triangles. So I will go with option 'd' None of these.

    Three parallel lines ,one from each set put together make a triangle, So the total number of triangles is

    5*6*4 = 120

    This is unfair. The parallel lines are similar and shouldn't be distinguished separately! All the parallel lines in one set are identical. SO you can't do 5*6*4 !!!
