Read Solution (Total 2)
-
- cp=re.1(milk) Re.0(water)
sp=125/100cp
cp=(100/125)*1
cp=4/5
1 0
4/5
4/5 1/5
4:1
% of water=1/5*100=20 - 9 years agoHelpfull: Yes(2) No(1)
20 gallons of 5% and 40 gallons of 2%..
(x*5)/100+{(60-x)*2}/100=60*3/100
x=20
so 20 gallons of 5%
and
40 gallons of 2%.- 10 years agoHelpfull: Yes(1) No(3)
