Its 27 if i am not not wrong

No. of dogs(d) is directly proportion to no of cans(c) and inversely proportion to time(t)

(d1*t1)/c1=(d2*t2)/c2 we have to find c2
(5*4)/3=(15*12)/c2
c2=27

5 dogs 3 cans 4 days
5 dogs 9 cans 12 days
15 dogs 27 cans 12 days
The powers of two are bloody impolite!!

Just convert into number of cans per dog per day: 3/(5x4)
so for 15 dog and for 12 days =( 3/(5x4)) x15 x12 = 27
