The data shown below shows the number of students in a school.
Std 1 - 25 students
std 2 - 20 students
std 3 - 18 students
std 4 - 17 students,
If the school has 27 (2) seaters to seat all the students in the classes, how many (2) seaters are needed to seat all the students?
* two seaters a desk for two children to sit in.
(25 + 20 + 18 + 17)/2 = ?
No fair, can not cut two person desk in half :)
Please check my reply below.
(25 + 20 + 18 + 17)/2 = 80 / 2 = 40
40 - 27 = 13 more two-seaters needed
I got 14
13 + 10 + 9 + 9 = 41
41 - 27 = 14
25/2 = 13
17/2 = 9
for two seaters
Ahh -- I see the problem. You're right, as usual, Damon. Thanks for clearing this up.
Although the total is 80 students, there are odd numbers of students in two classrooms.
To find out how many (2) seaters are needed to seat all the students, we need to calculate the total number of students and divide it by the number of students that can be seated in one (2) seater.
First, let's calculate the total number of students.
Total students = 25 (Std 1) + 20 (Std 2) + 18 (Std 3) + 17 (Std 4)
= 80 students
Next, we need to calculate how many (2) seaters are needed to seat all the students.
Since each (2) seater can accommodate two children, the total number of (2) seaters needed can be calculated by dividing the total number of students by 2 (since each (2) seater accommodates two children).
Total (2) seaters needed = Total students / 2
= 80 students / 2
= 40 (2) seaters
Therefore, to seat all the students in the classes, 40 (2) seaters are needed.
