Answer / raef mostafa
20% Alcohol represents 3 Ltrs from the 15 Lts Water
Water = 12 ltrs
By adding 5 more lts of water total water is 17 lts +
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%
