Question

please solve it....​

Answer 1

Given :

• Discount = 20%
• Gain = 12 %

To Find :

• percent above the cost price.

Solution :

Let the Cost price be ₹ 100 and Marked price be ₹x .

Gain % = 12%

Gain = 12% of ₹100 = 12/100 * 100 = ₹12

SP = Gain + CP

= 100 + 12

= 112

Discount % = 20%

Discount = 20% of Marked Price

= 20% * x

= 20/100 * x

= x/5

According to the question,

Marked Price - Discount = SP

x - x/5 = 112

4x/5 = 112

4x = 112 * 5

x = (112*5)/4

x = ₹140.

Marked Price = ₹140

Amount marked about the Cost price = Marked Price - Cost price

= ₹140 - ₹100

= ₹40

because percent above the Cost Price

= Amount increased/CP * 100

= 40/100 * 100

= 40%

Hence, percent above the cost price is 40%.
