Ashish leaves for his office from his house. He walks towards East. After moving a distance of 20 m, he turns South and walks 10 m. Then he walks 35 m towards the West and further 5 m towards the North. He then turns towards East and walks 15 m. What is the straight distance (in metres) between his initial and final positions ?

Options

A. 1. 0
B. 2. 5
C. 3. 10
D. 4. Cannot be determined

Answer

B

Explanation

The movements of Ashish are as shown in Fig. i.e. A to B, B to C, C to D, D to E and E to F.
`because` A = Starting Point
F= End Point

Clearly, DC= AB + EF
So, F is in line with A.
Also, AF= (BC-DE) = 5m
Therefore, Ashish is S metres away from his initial position.
