Answer 1

Answer:

20 % Hike in price

Step-by-step explanation:

the gain 8% after allowing a discount of 10% of by what percent cost price should be hicked in the list price​

Let say Cost Price = C

& Hiked by  H %  in List Price

Then List Price =  C + (H/100)C = C  + CH/100

Discount of 10 % = (10/100) (C  + CH/100)  = C/10  + CH/1000

Selling Price = C  + CH/100 - (C/10  + CH/1000)

= 9C/10  + 9CH/1000

8 % Gain on Cost Price = (8/100)C = 8C/100

Selling Price = C + 8C/100

9C/10  + 9CH/1000  = C + 8C/100

Dividing by C both sides

=> 9/10  + 9H/1000 = 1  + 8/100

Multiplying by 1000 both sides

=> 900 + 9H = 1000 + 80

=> 9H = 180

=> H = 20

20 % Hike in price
