Subject :IMO Class : Class 9

In the given figure, ABCD is a parallelogram. E and F are points on opposite sides AD and BC respectively, such that ED = 1/2 AD and BF = 1/3 BC. If ∠ADF = 60°, then find ∠BFD.

A120°
B130°
C125°
D115°

This question has a mistake as the solution explains be is parallel to df hence bf should be 1/2 of bc and not 1/3
