<p>If it takes 16 faucets 10 hours to fill 8 tubs, how long will it take 12 faucets to fill 9 tubs?
A. 10 hours
B. 12 hours
C. 13 hours
D 14 hours
E. 15 hours</p>
<p>let's suppose one faucet in one hour can fill x tub(s)
then 16<em>x</em>10=8
x=0.05
now suppose you'll need y hours for 12 faucets to fill 9 tubs
so likewise you get 12<em>0.05</em>y=9
y=15</p>
<p>Where did you retrieve this question?
B:
This is similar to that pig question.</p>
<p>10 hours * 16 faucets/12 faucets * 8 tubs/9 tubs = 12 hours</p>
<p>you get 12? it has to lead to the same answer...</p>
<p>10 hours * 16 faucets/12 faucets * 9 tubs/8 tubs = 15 hours</p>
