Problem 4

In parallelogram $ABCD$, point $M$ is on $\overline{AB}$ so that $\frac {AM}{AB} = \frac {17}{1000}$ and point $N$ is on $\overline{AD}$ so that $\frac {AN}{AD} = \frac {17}{2009}$. Let $P$ be the point of intersection of $\overline{AC}$ and $\overline{MN}$. Find $\frac {AC}{AP}$.

Solution

Solution

One of the way to solve this problem is to make this parallelogram a straight line.

So the whole length of the line$(AP)$ is $1000+2009=3009units$

And $AC$ will be $17 units$

So the answer is $3009/17 = 177$
