Solution:

Need to find: Find the average age of the remaining 12 players ?

  • Here,The average age of 20 players of a football team is 24. The average of 8 of them is 21.so we should find the average age of the remaining 12 players ?

Step-by-step explanation:

\\

\toaverage age of 20 players = sum of age of the 20 players / total no.of.players

\to 24 = sum of age of the 20 players / 20

\to sum of age of the 20 players = 24 × 20 = 480

\to \sf{average \: age \: of \: 20 \: players \: of \: a \: football \: team \:  =  \frac{sum \: of \: the \: age \: of \: 20 \: players}{total \:.no.of \: players}}

 \to \sf{21 =  \frac{sum \: of \: the \: age \: of \: the \: 8 \: players}{8}}

 \to \sf{sum \: of \: the \: age \: of \: the \: 8 \: players = 8 \times 21} \\ \\  \to \sf{sum \: of \: the \: age \: of \: the \: 8 \: players = 168}

  \to\sf{sum \: of \: the \: age \: of \: remaining \: 12 \: players = 480 - 168 = 312}

 \to \sf{Average  \: age  \: of remaining  \: 12  \: players = \frac{312}{12}} \\  \\ \to \sf{Average  \: age  \: of  \: remaining  \: 12  \: players = 26}

  • Therefore,The average age of remaining 12 players is 26.
