total mixture is 15 liters
out of which 20% is alcohol so total alcohol is=
20% of 15 liters= 20*15/100=3 liters
the rest is water,so water content= 12 liters
on adding 3 more liters of water,
the total water will be 15 liters and the alcohol will still be 3 liters.so the total mixture would be 18 liters.
so the alcohol percentage in new mixture
=3 liters out of 18
=3*100/18
=16.67%
