A) North-East
B) South-East
C) North-West
D) North
Correct Answer: C
Solution :
: The villager moves from his village at O to his uncle's village at A and then to his brother-in-law's village at B. Clearly, AOBA is right-angled triangle at B. So, \[O{{A}^{2}}=O{{B}^{2}}+A{{B}^{2}}\] \[\Rightarrow O{{B}^{2}}=O{{A}^{2}}-A{{b}^{2}}\] \[OB=\sqrt{(25-16)}km=\sqrt{9}km=3km\] Thus, B is 3 km to the east of his initial position 0.You need to login to perform this action.
