Question : Directions: A man goes 10 km westward, then turns right and proceeds 4 km, then travels 10 km towards left, then travels 8 km towards left, and finally goes 4 km northward. Calculate his distance from his initial place in the horizontal direction.
Option 1: 20 km
Option 2: 22 km
Option 3: 23 km
Option 4: 25 km
Correct Answer: 20 km
Solution : Firstly, we will draw the diagram as per the given instructions –
In the above figure, O is the starting point and E is the finishing point. So, OE is the distance from the starting point.
OE = OA + AE
Also, AE = BC = 10
OE = 10 + 10 = 20 km
So, the distance from the starting point is 20 km. Hence, the first option is correct.
