Options

A. 10 metres
B. 15 metres
C. 20 metres
D. 5 metres

Answer

D

Explanation

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

Clearly, FE =AB + CD
So, F is in line with A.
Therefore, Sonam.s distance from the starting point
A=AF= (DE-BC)
= (15 - 10) m = S m
