medium
A tradesman gives $4 \%$ discount on the marked price and gives one article free for buying every $15$ articles and thus gains $35 \% .$ The marked price is appox. how much percent above the $CP$?
A
$20$
B
$30$
C
$40$
D
$50$
Solution
Let the $CP$ of each article be $Rs. 100$ Then $CP$ of $16$ articles $=$ Rs. $(100 \times 16)=1600$
$SP$ of $16$ articles $=1600 \times \frac{135}{100}=$ $Rs. 2160$ ($1$ article free)
$SP$ of each article $=\frac{2160}{16}=$ $Rs. 135$ If $SP$ is $Rs. 96,$ marked price $= Rs. 100$ If $SP$ is Rs. $135,$ marked price
$=\frac{100}{96} \times 135=$ $Rs. 140.625$
Therefore marked price $\approx40 \%$ above $CP$
