Problem Analysis

We are given the information that there were passengers in a bus. When 10 passengers got off at a stop and 3 passengers got on, the total number of passengers in the bus became 12. We need to determine the number of passengers in the bus before the stop.

Solution

Let's assume the number of passengers in the bus before the stop was x.

According to the given information: - When 10 passengers got off, the number of passengers decreased by 10: x - 10. - When 3 passengers got on, the number of passengers increased by 3: x - 10 + 3. - The resulting number of passengers after the stop was 12: x - 10 + 3 = 12.

To find the value of x, we can solve the equation:

x - 10 + 3 = 12

Simplifying the equation:

x - 7 = 12

Adding 7 to both sides of the equation:

x = 12 + 7

Therefore, the number of passengers in the bus before the stop was 19.

Answer

There were 19 passengers in the bus before the stop.
