Question

В автопарку було 120 легкових автомобілів,вантажівки та автобуси.Вантажні автомобілі становили 65% від кількості легкових і 13/15 від кількості автобусів.Скільки транспортних одиниць було в автопарку?

Answer 1

1) 120 : 100 * 65 = 78 - грузовики

2) 78 = 13/15 от  количества автобусов (15/15). Находим целое по его части:

    78 : 13 * 15 = 90 - автобусы

3) 120 + 78 + 90 = 288 - транспортных единиц

Ответ: в автопарку було 288 транспортних одиниць

Answer 2

Calculation of the Number of Vehicles in the Fleet

To determine the number of vehicles in the fleet, we need to calculate the number of trucks, buses, and cars separately and then add them together.

Let's start with the given information:

- There were 120 vehicles in the fleet, including cars, trucks, and buses. - Trucks accounted for 65% of the total number of cars. - Trucks accounted for 13/15 of the total number of buses.

To calculate the number of trucks, we can use the percentage given:

Number of trucks = 65% of the total number of vehicles

To calculate the number of buses, we can use the fraction given:

Number of buses = (13/15) * total number of trucks

Finally, we can calculate the number of cars:

Number of cars = total number of vehicles - (number of trucks + number of buses)

Let's perform the calculations step by step:

1. Calculate the number of trucks: - Number of trucks = 65% of 120 vehicles - Number of trucks = 0.65 * 120 - Number of trucks = 78

2. Calculate the number of buses: - Number of buses = (13/15) * 78 trucks - Number of buses = (13/15) * 78 - Number of buses = 67.6 (rounded to the nearest whole number) - Since we cannot have a fraction of a vehicle, we round down to 67 buses.

3. Calculate the number of cars: - Number of cars = 120 vehicles - (78 trucks + 67 buses) - Number of cars = 120 - (78 + 67) - Number of cars = 120 - 145 - Number of cars = -25

Based on the calculations, we have a negative number for the number of cars, which doesn't make sense in this context. It seems there might be an error or inconsistency in the given information or calculations.
