Question

If a merchant makes a profit of 20 after giving a 20 discount what should be his mark-up

Answer 1

(1 + m/100)*(1 - d/100) = (1 + p/100)

(1 + m/100) * ( 1 - 20/100) = (1 + 30/100)

(1 + m/100) = 13/8 = ( 1 + 5/8)

m = 62.5

Answer 2

Answer:Rs.150/Increase%=50%

Step-by-step explanation:

Let C.P=100

Then, S.P=(20/100)×100+100

          S.P=120

Let M.P=X

S.P=M.P-Discount

120=X-(20/100)X

120=8X/10

1200=8X

X=150

Increase%=50%
