Answer 3

Calculating the Number of Wagons in the Freight Train

To calculate the number of wagons in the freight train after uncoupling and coupling, we can use the following steps:

1. Initial Number of Wagons: The initial number of wagons in the freight train was 54. 2. Uncoupled Wagons: 12 wagons were uncoupled from the train at the station. 3. Coupled Wagons: 15 wagons were coupled to the train at the station.

Calculation

To find the final number of wagons in the freight train, we can use the following formula: Final Number of Wagons = Initial Number of Wagons - Uncoupled Wagons + Coupled Wagons

Solution

Final Number of Wagons = 54 - 12 + 15 Final Number of Wagons = 57

Therefore, after uncoupling 12 wagons and coupling 15 wagons, the total number of wagons in the freight train became 57.
