The average weight of $5$ persons, sitting in a boat, is $38 \,Kg$. If the average weight of the boat and the persons sitting in the boat is $52 \,Kg$, what is the weight of the boat? (in $kg$)

A

$228$

B

$122$

C

$232$

D

$242$

Solution

Average weight of $5$ persons $=38 Kg$

Total weight of these five persons

$=38 \times 5=190 Kg$

Now, average weight of (the boat $+$ $5$ persons)

$=52 Kg$

Total weight of (the boat $+$ $5$ persons) $=52 \times 6=312 Kg$

$\therefore$ Weight of the boat $=312-190=122 Kg$
