Question

When an article is sold at a discount of 10%, a profit of Rs. 8 is
earned. If the same article is sold without allowing discount, there
will be a profit of Rs. 20. Find the cost price of
the article.​

Answer 1

Rs 100

Step-by-step explanation:

market price = MP

cost price = CP

P1 = (MP-10%) - CP= RS 8

- CP = RS 8 - 0.90%MP

CP = 0.90 MP - RS 8

P2 = MP - CP = RS 20

-CP = RS20 - MP

CP = MP - RS 20

0.90 MP - RS 8 = MP - RS 20

- 0.10% MP = - RS 12

0.10% MP = RS 12

MP = RS 120 P

CP =MP - RS 20 = RS 120 - RS 20 =RS 100

THE COST PRICE OF THE ITEM IS RS 100
