Given a triangle with side AB = 8 cm. To get a line segment AB' = 3/4 of AB, it is required to divide the line segment AB in the ratio:
3 : 1
4 : 3
1 : 3
3 : 4
Points P and Q are in the line segment AB and on the same side of its midpoint. P divides AB in the ratio 2:3 and Q divides AB in the ratio 3:4. If PQ=2 cm, then find the length of the line segment AB.
