Hemant purchased $120$ rims of paper at $Rs.\,80$ per rim. He spent $Rs.\,280$ on transportation, paid octroi at the rate of $40$ paise per rim and paid $Rs.\,72$ to the coolie. If he wants to have a gain of $8 \%,$ the selling price per rim must be (in $Rs.$)
A
$89$
B
$90$
C
$95$
D
None of these
Solution
We have,
cost price $( C . P )=(120 \times 80+280+72+120 \times 40)$
$=Rs. 10000$
$\operatorname{Gain} \%=8 \%$
$\therefore$ Selling Price $(S.P.)$ of $120$ rims $=\left(\frac{100+\operatorname{Gain} \%}{100}\right) \times C.P.$
$=\left(\frac{100+8}{100}\right) \times 10000$
$=\frac{108}{100} \times 10000=Rs. 10800$
Thus, selling price per rim $=\frac{10800}{120}=Rs. 90$
