Four students were added to the dance class. Would the teacher be able to divide her students evenly into a dance team/s of 8?

(1) If 12 students were added the teacher could put everyone in team of 8 without any leftovers.
(2) The number of students in the class is currently not divisible by 8.

Let number of students be x

(x+4)=8n? [n is an integer and groups of 8 students]

stmt1,

(x+12)=8n

x+4=8n-8

x+4=8(n-1)

x+4 is multiple of 8.

Suff

stmt2,

x is not divisible by 8.

x=8n+r

We don't know the remainder.

Insuff

Pick A
