Challenge problem. who ever gives best explanation with correct answer gets brainliest answer! in a school 50% of the students are younger than 10, 1/20 are 10 years old and 1/10 are older than 10 but younger than 12, the remaining 70 students are 12 years or older. how many students are 10 years old?

They are 10 students
The remaining 70 students comprise 35% of the total no. of students. This means that the school has a total of 200 students.
1/20 of 200 is 10 students.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
