Explanation

Mixture 1: 1 part lemon, 1 part sugar (ratio 1:1). Mixture 2: 1 part Mixture 1, 3 parts sugar. Total lemon = 1/2 part. Total sugar = 1/2 (from Mix 1) + 3 = 3.5 parts. Ratio = 0.5 : 3.5 = 1 : 7.

AI explanation

Assume the original mixture is 4 units, consisting of 2 units of lemon juice and 2 units of sugar syrup. When combined with 12 units of pure sugar syrup in a 1 to 3 ratio, the new total amounts are 2 units of lemon juice and 14 units of sugar syrup. This yields a final ratio of lemon juice to sugar syrup of 1 to 7.
