medium
A white goods dealer pays $10 \%$ custom duty on an i-phone that costs $Rs.\, 25000$ in $UK$. For how much should hemark it, if he desires to make a profit of $20 \%$ after giving a discount of $25 \%$ to the buyer? (in $Rs$)
A
$32000$
B
$38000$
C
$44000$
D
Cannot be determined
Solution
$CP$ of i-phone to dealer (on inclusion of $10 \%$ custom duty)
$=$ Rs. $(25000+10 \%$ of $25000$)$= Rs. 27500$
The $SP$ of i-phone at $20 \%$ profit $=$ $Rs.$ $\left[27500 \times \frac{120}{100}\right]=$ $Rs. 33000$
But Here, $Rs. 33000$ is price after $25 \%$ discount on $MP$ Hence, MP $\times(1-0.25)=33000$
$MP =\frac{33000}{0.75}= Rs .44000$
