ratio of discount offered to the CP = 39 : 70 if Discount & Profit % = 30%
Step-by-step explanation:
Let say Marked Price = M
Discount = 30 %
Discount = (30/100) M = 0.3M
Selling Price = M - 0.3M = 0.7M
Cost Price = C
Profit = 30 %
Profit = (30/100)P = 0.3C
Selling Price = C + 0.3C = 1.3C
1.3C = 0.7M
=> M = 13C/7
Discount offered = 0.3M
= 0.3 (13C/7)
= 39C/70
ratio of discount offered to the CP = 39 : 70
