Problem Analysis

We are given that a certain number of passengers got off a bus at a stop, and the number of passengers remaining on the bus is three times the number of passengers who got off. We need to determine the total number of passengers on the bus.

Solution

Let's assume the number of passengers who got off the bus is represented by the variable 'x'. According to the problem, the number of passengers remaining on the bus is three times the number of passengers who got off. Therefore, the number of passengers remaining on the bus can be represented as '3x'.

To find the total number of passengers on the bus, we need to add the number of passengers who got off to the number of passengers remaining on the bus. This can be expressed as:

Total number of passengers = Number of passengers who got off + Number of passengers remaining on the bus

Mathematically, this can be written as:

Total number of passengers = x + 3x

Simplifying the expression, we get:

Total number of passengers = 4x

Now, we are given that 'k' is equal to 12. Therefore, we can substitute 'k' with 12 in the expression for the total number of passengers:

Total number of passengers = 4k

Substituting k = 12, we get:

Total number of passengers = 4 * 12 = 48

Therefore, there were 48 passengers on the bus.

Answer

The total number of passengers on the bus was 48.
