DIRECTIONS for the question: Solve the following question and mark the best possible option.
Radha moves towards South-east a distance of 7 km , then she moves towards West and travels a distance of 14 m. From here, she moves towards North-west a distance of 7 m and finally she moves a distance of 4 m towards East and stood at that point.
How far is the starting point from where she stood?
Solution
The person first travelled from A to B for 7 kms then travelled to C for 14kms and then to D for 7kms again.
The quadrilateral ABCD formed from this movement is a parallelogram and thus BC should be equal to AD i.e. 14 kms.
Now, he travelled from D to E(towards East) for 4kms. This means that the distance between starting point i.e. A and E is 14- 4 = 10 kms.
