At a summer fair, 18 ml of lemon syrup was mixed with 120 ml of water to prepare Lemonade A, 30 ml of syrup was mixed with 250 ml of water for Lemonade B, and 15 ml of syrup was mixed with 75 ml of water for Lemonade C. Considering the syrup-to-water ratio as a measure of sweetness, how does Lemonade B compare to the others?
(a) Has equal sweetness as Lemonade A
(b) Has the highest sweetness among all
(c) Is less sweet than Lemonade C
(d) Is sweeter than Lemonade A

Question

At a summer fair, 18 ml of lemon syrup was mixed with 120 ml of water to prepare Lemonade A, 30 ml of syrup was mixed with 250 ml of water for Lemonade B, and 15 ml of syrup was mixed with 75 ml of water for Lemonade C. Considering the syrup-to-water ratio as a measure of sweetness, how does Lemonade B compare to the others?
(a) Has equal sweetness as Lemonade A
(b) Has the highest sweetness among all
(c) Is less sweet than Lemonade C
(d) Is sweeter than Lemonade A

ONLiNE UPSC · Accepted Answer

We calculate the sweetness ratio (syrup &divide; water) for each lemonade:
Lemonade A: 18/120 = 0.15
Lemonade B: 30/250 = 0.12
Lemonade C: 15/75 = 0.20
Now compare:
B (0.12) vs A (0.15) &rarr; B is less sweet
B (0.12) vs C (0.20) &rarr; B is less sweet

Hence, option c is correct.
