Solution
The correct option is B8350m Distance covered by justin =7.34 m
Required distance for qualification in finals =9 m
Distance by which justin is behind =(9−7.34) m =1.66 m
But, it is asked to calculate the distance in fraction so on converting 1.66 m into fraction we get, ⇒1.66=166100⇒1.66=83×250×2⇒1.66=8350
So, distance by which justin is behind the mark is 8350 m.
