In quadrilateral ABCD, −−→AB=→a, −−→BC=→b, −−→AD – InterviewSolution

1.	In quadrilateral ABCD, −−→AB=→a, −−→BC=→b, −−→AD=→b−→a. If M is the mid point of −−→BC and N is a point on −−→DM such that −−→DN=45−−−→DM, then −−→AN=
Answer» In quadrilateral $A B C D, - - \to A B = \to a, - - \to B C = \to b, - - \to A D = \to b - \to a .$ If $M$ is the mid point of $- - \to B C$ and $N$ is a point on $- - \to D M$ such that $- - \to D N = \frac{4}{5} - -- \to D M,$ then $- - \to A N =$
