Answer 1

Answer:

Step-by-step explanation:

8) Let the cost price = 100

Marked Price = 120

Discount percent = 15%

$Selling \ price = \dfrac{100-15}{100}*120\\\\=\dfrac{85}{100}*120\\\\= 102$

Gain = Selling price -  Cost price

       = 102 -100

      =2

$Gain \ percent = \dfrac{2}{100}*100$

                      = 2%

9) Marked Price = ₹ 220

Discount % = 10%

$Selling price =\dfrac{100-10}{100}*220\\\\=\dfrac{90}{100}*220$

= ₹ 198

$Cost \ price = \dfrac{100}{100+10}*198\\\\=\dfrac{100}{110}*198$

Cost price = ₹ 180
