alcohol 3 ltrs
Which represent approx.6%

Answer / techbots

15 ltrs water containing 20% alcohol means

say the water contents are X ltrs

then alcohol contents would be 0.2X ltrs

so X+ 0.2X = 15 ltrs

so X=1.25 ltrs

now add 5 ltrs of water so total volume will be 20 ltrs

so now the % is 1.25*100/20 = 6.25%

15lts water =20%
5 lts add
total=15+5=20
20tls=x
15x=20*20
15x=400
x=400/15
x=26.666
