The quantity you want is 10 pints. Let's call the unknown quantity of .01 x. Then, the quantity of .04 will be 10-x.
----------------------
.01x+.04(10-x)= .02(10)
.01x+.4-.04x= .2
-.03x= -.2
x= -.2/-.03 Negative divided by negative = positive:
x= 6.67 pints of .01(1%) solution mixed with
10-6.67= 3.33 pints of .04 solution
