A school has 1000 students. Half of the students were taken on a trip to the nearby beach. Half of the remaining students were sent home. How many students are still in the school?
Please answer and provide answer explanation.
250
1000 * 1 / 2 = 500 students were taken on a trip to the nearby beach.

So 1000 - 500 = 500 students were not taken to the beach.

Thus, 1 / 2 * 500 = 250 students who were not taken to the beach were sent home.

Thus, 500 - 250 = 250 students are still in school.

.

So, the final answer is 250
