the SP and discount % equals profit
% then find the ratio of discount
offered to the CP?​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

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
