**Steve**, Saturday, November 17, 2012 at 6:23amacid in 400L 38% = 152

acid in 400L 65% = 260

if the 3 solutions were wanted in the amounts a,b,c respectively, then

a+b+c = 400

.3a + .4c + .8b = 260

.3a + .4b + .8c = 152

a = 340/3

b = 835/3

c = 25/3

check my results to make sure they fit the conditions.
