$19$ persons went to a hotel for a combined dinner party. $13$ of them spent $Rs.\, 79$ each on their dinner and the rest spent $Rs.\, 4$ more than the average expenditure of all the $19 .$ What was the total money spent by them.
A
$1628.4$
B
$1534$
C
$1492$
D
$1536.07$
Solution
Let the Average expenditure of the party is $x$
$13 \times 79+6(x+4)=19 \times x$
$13 x=13 \times 79+24 \Rightarrow x=\frac{1027+24}{13}=80.84$
Total expenditure of the party $=80.84 \times 19=1536.07$
