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.
Please check my reply below.
(25 + 20 + 18 + 17)/2 = 80 / 2 = 40
40 - 27 = 13 more two-seaters needed
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
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.
