Question

There were some people on a bus. Half of the people get off at the first stop and 11 people get on. Now there are 20 people on the bus. How many people were on the bus to begin with?

Answer 1

Answer:

There were 18 people in the bus in the beginning.

Step-by-step explanation:

Let the people were in the beginning be x

Half of the people get off i.e., x/2

And 11 people added i.e., x/2 + 11

Now it is 20 people

According to the question,

⟹ x/2 + 11 = 20

⟹ x/2 = 20 - 11

⟹ x/2 = 9

⟹ x = 9 × 2

⟹ x = 18 ans.
