Correct Answer: 9 km


Solution : Firstly, we will draw the diagram as per the given instructions –

Now, we have to find the distance the person has to travel to reach the post office after lunch.

In the figure, A is the starting point and E is the finishing point. So, AE is the distance from the starting point.
Here, AB = CD = 3 km and BC = AD = 4 km
So, AE = AD + DE
 AE = 4 + 5 = 9 km

So, the person has to travel 9 km to reach the post office after lunch. Hence, the third option is correct.
