Question

If the discount and profit percentage are both 20% by
what percent is the marked price above the cost price?​

Answer 1

Answer:

Marked Price is 50% above Cost Price

Step-by-step explanation:

Let

CP = Cost Price

MP = Marked Price

SP = Selling Price

Given

Discount = 20%

=> SP is 20% less than MP

=> SP is 80% of MP

=> SP = 0.8*MP ......(i)

Profit = 20%

=> SP = 20% more than CP

=> SP = CP + (20% of CP)

=> SP = CP + 0.2*CP

=> SP = 1.2*CP ..........(ii)

From (i) and (ii), we get:

0.8*MP = 1.2*CP

=> MP = (1.2/0.8)*CP

=> MP = 1.5*CP

=> MP = CP + 0.5*CP

=> MP = CP + 50% of CP

=> MP is 50% more than (or above) CP

Answer 2

Answer:

50%

Step-by-step explanation:

(d)discount = 20%

(p) profit = 20%

let cost price (c. p) = 100

selling price (s. p) = c. p+profit (p)

s. p = 100 + 20 = 120

discount = 20% so, remaing 80% t

there. so Marked price (M. P) i

is 80% that is 80x.

S. P = 80x/ 100

120 = 80x ÷ 100

(M.P) x = 150

Marked price more or above the cost price

M. P = C. P + 50 % C. P

150 = 100+50

so, Ans = 50%
