Question

a school organized three different trips. 50% of the students went on 1st trip, 80% went on the second trip and 90% went on the third trip. a total of 160 students went on all the three trips. how many students are at the school​

Answer 1

To find the total number of students at the school, double the number of students who went on all trips, resulting in 320 students.

Step-by-step explanation:

The question asks us to determine the total number of students at a school given that 50% went on the first trip, 80% on the second trip, and 90% on the third trip, with a total of 160 students attending all three trips.

Here's how this problem can be solved:

1. We are told that the same group of students, which is 160 students, went on all three trips.
2. Since these students represent 50% of the school population on the first trip, we can establish that if 50% equals 160 students, then 100% (the total school population) would be twice as many, because 50% is half of 100%.
3. Therefore, doubling the 160 students gives us 320 students as the total school population.
