Question

The weight of four rowers of a boat are respectively 70kg, 73kg,
72kg and 74kg and the average weight of whole crew, including the
coxswain is 70kg Find the weight of the coxswain

Ashwini Kumar · Accepted Answer

Let the weight of coxswain is x km
Therefore, 70+73+72+74+x5=70⇒289+x5=70⇒289+x=350⇒x=350-289∴x=61Hence, weight of coxswain is 61 km

The weight of four rowers of a boat are respectively 70kg, 73kg, 72kg and 74kg and the average weight of whole crew, including the coxswain is 70kg. Find the weight of the coxswain.
