7.Profit and Loss
medium
A shopkeeper allows a discount of $10 \%$ on the marked price of an item but charges a sales tax of $8 \%$ on the discounted price. If the customer pays $Rs.\, 3,402$ as the price including the sales tax, then the marked price is (in $Rs.$)
A
$3400$
B
$3500$
C
$3600$
D
$3800$
Solution
$MP.$ $=100 x$
$D \%=10 \%(100 x)=10 x$
$\therefore S.P. =90 x$
Sales tax on discounted price $=8 \%(90 x)=7.2 x$
Now, total $S.P.$ $=90 x+7.2 x=97.2 x$
If $97.2 x=3402$
$x=35$
$\therefore MP.=100 \times 35=3500$
