Options:
A) 5 km
B) 10 km
C) 40 km

Solution:

Ans:(b)

Suppose my house is at P. from P Ram walks 15 km towards West and reaches Q. At Q he turns left and walks 20 km to reach R. At R, he turns east and walks 25 km to reach S. At S, he turns left and walks 20 km to reach T. It is evident from the figure that:

TP=TQ-PQ and TQ=RS 

TP= RS-PQ = 25-15=10 km
