Question

A trader Mark's his good at 50 percent above the cost price but allows a discount of 20 percent on the market price. Calculate his gain percent.

Answer 1

50 percent of cost price
20 percent discount
50-20 = 30 percent as gain percent
it also can be more than 30 but here no cost price or selling price is given
So gain or profit percent is 30 percent

Answer 2

$\sf \: 20\%$

GiVen:-

• Discount =20 %

AnSwer:-

Here,

Let the original C.P. be Rs. 100.

Then,

$\sf \: The \: marked \: price : - \\ \implies\sf \ \: 50\% \: of \: 100+100=150$

$\sf \: Selling \: Price \: (SP) : - \\ \implies \sf \: 150 - 20\% \: of \: 150 \\ \implies \sf \:150 - 30 \\ \implies \sf \:120$

Now,

$\sf \: Profit\% = \dfrac{(120 - 100) \times 100}{100} \\ \\ \implies \sf \: \frac{20 \times 100}{100} \\ \\ \implies \sf \:20\%$
