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
