Question

On selling a pen for ₹48, a shopkeeper loses 20%. In order to gain 20% what should be the selling price?​

Answer 1

GIVEN DATA,

SP = 48

CP = ?

LOSS = 20%

PROFIT = 20%

LET CP = X

SP = 100% - 20% ( IT IS LOSS)

SP = 80%

= 80% * X = 48

80x ÷ 100 = 48

x = 48 × 10 ÷ 8

x = ₹60

CP is ₹60

20% profit

Profit = 20% of CP

=20 ÷ 100 × 60

= ₹72

Answer 2

Answer:

72

Step-by-step explanation:

20% of loss = 20/100 => 1/5

CP SP

5 : 4

4 ratio = 48

1 ratio = 48/4 = 12

then CP of pen is 5*12 = 60

20% profit at 60

60*20/100 = 12

Selling price = CP+Profit = 60+12 = 72
