Question

after allowing a discount of 10% there was still a gain of 5%. at what per cent above the cost price was the marked price ?​

Answer 1

Answer:16.666% above the Cp

Step-by-step explanation:

Let the cp be ₹x.

Sp including gain=

105% of x=21x/20

90% of Sp=21x/20

90*Sp/100=21x/20

Sp=21x*100/90*20

Sp=21x*5/90

Sp=21x/18

Sp=7x/6

It means Sp=(7*100/6)% of x

116.666% of x

Therefore, the marked price should be (116.666-100)% above the Cp

16.666% above the Cp
