In a cricket team of $11$ boys, one player weighing $42 \,kg$ is injured and replaced by another player. If the average weight of the team is increased by $100\, gm$ as a result of this, then what is the weight of the new player? (in $kg$)

A

$42.1$

B

$45.1$

C

$44.1$

D

$43.1$

Solution

Average weight of $11$ boys is increased by $100 gm$ $(=0.1 Kg )$

$\therefore \quad$ Their total increase in weight

$=0.1 \times 11=1.1 \,kg$

Hence, the weight of the boy $=42+1.1=43.1 \,kg$.
