• # question_answer 10) Raj travelled from a point X straight to Y at a distance of 80 meters. He turned right and walked 50 metres, then again turned right and walked 70 metres. Finally, he turned right and walked 50 metres. How far is he from the starting point? A) 10 metres    B) 20 metres C) 50 metres                     D) 70 metres

The movements of Raj are as shown in fig (X to Y, Y to A, A to B, B to C). $\therefore$ Raj's distance from the starting point $=XC=\text{ }\left( XY-YC \right)=\text{ }\left( XY-BA \right)$ $=\left( 80-70 \right)m=10m.$
