Let value of A be 3
such that 4A ; 12 and 3 students are left behind means that total 9 students are in groups
later A/3 ; 3/3 ; 1 group such that no student is left behind
I. If the students are distributed into groups that contain A+ 1 students each, the number of students that are left without a group can be 2
A+1 ; 4 this is not sufficient as 4*4 ; A/3 ; 1 student is left behind ; incorrect
II. If the students are distributed into groups that contain 3 students each, no students are left without a group
A has to be factor of 3 A/3 will always leave no student without a group correct
III. If the students are distributed into groups that contain 12 students each, 9 students are left without a group
This cannot be correct as 12 *x ; or 12*x/3 will always leave no students behind ; incorrect
option II is only correct
option B
