Calculation of Bicycles in Detskiy Mir

To determine the number of three-wheeled bicycles sold in Detskiy Mir, we can use the information provided: there are a total of 12 handlebars and 27 wheels.

According to the given information, each bicycle has two handlebars and two wheels. Therefore, we can calculate the number of two-wheeled bicycles by dividing the total number of handlebars by 2, and the number of wheels by 2.

Let's calculate it step by step:

1. Number of two-wheeled bicycles: - Total handlebars: 12 - Number of handlebars per two-wheeled bicycle: 2 - Number of two-wheeled bicycles = Total handlebars / Number of handlebars per two-wheeled bicycle = 12 / 2 = 6.

2. Number of wheels used by two-wheeled bicycles: - Total wheels: 27 - Number of wheels per two-wheeled bicycle: 2 - Number of wheels used by two-wheeled bicycles = Total wheels / Number of wheels per two-wheeled bicycle = 27 / 2 = 13.5.

Since we cannot have half a bicycle or half a wheel, we can conclude that the number of two-wheeled bicycles sold is 6, and they used 13 wheels.

To find the number of three-wheeled bicycles, we can subtract the number of two-wheeled bicycles from the total number of bicycles:

Number of three-wheeled bicycles = Total number of bicycles - Number of two-wheeled bicycles = Total number of wheels - Number of wheels used by two-wheeled bicycles = 27 - 13 = 14.

Therefore, Detskiy Mir sold 14 three-wheeled bicycles.

Please note that the calculation assumes that each bicycle has two handlebars and two wheels, as stated in the given information.
