Solution
The correct option is C 100 metres
Rakesh's position from finishing line = 800 m - 40 m = 760 m
Avinay's position from finishing line = 760 m - 20 m = 740 m
Sunil's position from finishing line = 740 m - 40 m = 700 m
Therefore, Sunil is 100 metres behind from the finishing line.
We could also have subtracted 40 m + 20 m + 40 m = 100 m from 800 metres.
Rakesh's position from finishing line = 800 m - 40 m = 760 m
Avinay's position from finishing line = 760 m - 20 m = 740 m
Sunil's position from finishing line = 740 m - 40 m = 700 m
Therefore, Sunil is 100 metres behind from the finishing line.
We could also have subtracted 40 m + 20 m + 40 m = 100 m from 800 metres.
