Question

A dealer gains 15% after selling an item at 10% discount on the printed price. Find the ratio of the cost
price to the printed price of the item.​

Answer 1

Answer:

18:23

Step-by-step explanation:

Let the printed price of item be Rs. 100.

After discount of 10% SP = Rs. 90 profit earned =15%

C.P of item = (115/100) ×90= (1800/23)

Hence, CP : Printed Price = (1800/23) : 100

=18:23

Answer 2

Answer:

Let the printed price of item be Rs. 100.

After discount of 10% SP = Rs. 90 profit earned =15%

C.P of item = 100 / 115 × 90 = 1800 / 23

Hence, CP : Printed Price = 1800 / 23 : 100=18:23.
