In a boutique, items were put in a showcase, and each was assigned a price for January. Each month after that, the price was 10 percent less than the price for the previous month. What is the ratio of the price of an item in April to the price of the same item in January

The ratio of price for an item in the month of April to January is = 9 : 10

Step-by-step explanation:

Let price of an item in January = 100

Given that the price for the next month is 10% less than the price for the previous month.

Therefore the price for the month of Feb = 90

Price for the month of march = 81

Price for the month of April = 72.9

Therefore the ratio of price for an item in the month of April to January

= 9 : 10
