Question

What will be the cost of a product if 20% discount is given on the marked price Rs 100.​

Answer 1

Answer:

Rs 20.

Step-by-step explanation:

GIVEN = 20%

= 20÷100

= 0.20

therefore, market price = Rs100

= 100 × 0.20

=Rs 20.

Answer 2

Given: Cost price of a product is Rs 100 & discount percentage is 20%.

Need to find: Selling price of the product?

⠀⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

❍ Let's consider Sp as x.

⠀⠀⠀⠀⠀

As we know that,

⠀⠀⠀⠀⠀

$\begin{gathered}\star\:{\underline{\boxed{\frak{SP = MP \left ( \dfrac{100- D}{100} \right )}}}}\\\\\\ \bf{\dag}\:{\underline{\frak{Putting\:given\:values\:in\:formula,}}}\\\\\\ :\implies\sf 100 \left ( \dfrac{100 - 20}{100} \right)\\\\\\ :\implies\sf \frac{10 \cancel{0} \times 8 \cancel{0}}{1 \cancel{0} \cancel{0}} \\\\\\ :\implies\sf 10 \times 8\\\\\\ :\implies{\underline{\boxed{\frak{\purple{ x = Rs \: 80}}}}}\:\bigstar\\\\\end{gathered}$

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

Therefore,

⠀⠀⠀⠀⠀

Cost price, x = 80 Rupees.

⠀⠀⠀⠀⠀

$\therefore\:{\underline{\sf{Hence,\:Cost \: price \: of \: the \: product\:is\:\bf{Rs \: 80}\: \sf{respectively}.}}}$
