Question 168

Manoj started from Point A and walked 18 m towards North. He then took two consecutive left turns and walked 5 m after taking each turn, He again took a left turn, walked 5 m and reached point B. How far is point A from point B ?

Solution

After walking 18m towards north from point A, lets say he reached point C. => AC = 18

After taking two consecutive left turns of 5m each, he reached point B.

=> CBA are collinear in that order.

=> BC = 5m

Now, distance between A and B = 18-5 = 13m
