2 lines are skew if they are neither parallel, nor intersecting.

If 2 lines are parallel or intersecting, they form a plane, so they are coplanar. So "skew" is the opposite or complement  of "coplanar".

i) a and b: are both on M so coplanar, not skew

ii) b is in M, c is in N and they have no common point, so skew. (if they had a common point that would be a point in the line d of intersections of planes M and N, but they dont meet at such a point)

iii) b and e: are both on M so coplanar, not skew

iv) e and c : skew, same argument as ii. 

v) a and e : are both on M so coplanar, not skew

vi) a and c: a is in M, c is in N. If they met, they would met at a point on line d, the only set of points common to planes M and N, but they dont. so skew

maxonik [38]

Children =

We can already make the estimation that the amount of children will be below 50. So by trial and error you will get to your answer by substituting with 41.

Children - 41

Women - 41 x 2 = 82

Men - 41 x 5 = 205

205 + 41 + 82 = 328

So your answer is <u>41</u>
