Question : Directions: A bus starts from point A and runs 20 km towards the south, then turns to its right and runs 25 km. It then turns right again and runs 20 km. Afterwards, it runs 5 km in the east direction and reaches point D. How far is the bus from the starting point?
Option 1: 35 km
Option 2: 20 km
Option 3: 25 km
Option 4: 30 km
Correct Answer: 20 km
Solution : Firstly, we will draw the diagram as per the given instructions in the question –
In the above figure, A is the starting point and D is the endpoint. So, AD is the required distance from the starting point.
AD = AE – ED
But, AE = BC = 25
AD = 25 – 5 = 20 km
So, the bus is 20 km from the starting point. Hence, the second option is correct.
