If I do not edit my post, is 378 + 675 not a possible answer?kstv wrote:378 = 14 x 27
625 = 25 X 27
So each section can have 27 students
No of section 14 + 25

So, does the question need any edit that could force us to consider GCD only?kstv wrote:you mean how many students (Plural). You can have 3, 9 students also in each section but whats the point.
