Question : Directions: Rama left home and walked 5 km southwards turned right and walked 2 km and turned right and walked 5 km. Then turned left and walked 5 km. How many kilometres will she have to walk to reach her home straight?
Option 1: 5
Option 2: 7
Option 3: 17
Option 4: 15
Correct Answer: 7
Solution : Firstly, we will draw the diagram as per the given instructions and then find the distance between the starting point(A) and the endpoint (E) covered by Rama –
From the above diagram, AB = CD = 5 km; BC = AD = 2km; DE = 5 km
AE = AD + DE
AE = 2 + 5 = 7 km
So, Rama needs to walk 7 km straight to reach her home. Hence, the second option is correct.
