ver .4n
gin .6n
add is x ounces of gin
ver .4n
gin .6n + x
hence equations becomes
.4n / (n+x) = .25
solve it and you will get x = 3n/5
or the other equation will be
(.6n + x) / (n+x) = .75
solve it and you will get x = 3n/5
You can also solve this by sample values
lets say total vol = 100 (=n)
ver = 40
gin = 60
now we want 40 to become 25%
that means total has to be 160
so we need to add 60 ounces of gin
60 is actually 3/5 of 100
so ans
