Question

81. Going 500 m towards east first and then 200 m back is same
as going 200 m towards west first and then going 500 m back​

Answer 1

Yes, here's why

Because  east and west are two opposite directions

so when going 500 m east and then coming 200 m back , we are at 500-200 = 300m east  

and in other case

Going 200 m west and then coming 500 back , we are at 200 -500 = 300 m east

Answer 2

Yes its Right

As 500 m to east and 200 m back is 300m east
And

200 m towards west and 500 back will also give us 300 m east
