Answer:

16

Step-by-step explanation:

Students                      8       x

Time taken (hours)     18     18 - 12 = 6

If number of students increases, the work will completed in less hours.

So inverse proportion

[tex]x =\frac{18*8}{6}=3*8 = 24[/tex]

Additional students required = 24 - 8 = 16
