Question

In a coffee shop, the following coffee samples are prepared for customers.

i. 10 g of sugar added to 100 g of coffee
ii. 10 g of sugar added to 200 g of coffee
iii. 4 g of sugar added to 200 g of coffee
iv. 4 g of sugar added to 100 g of coffee

Based on the amount of sugar added, which sequence ranks the coffee from the sweetest coffee to the least-sweet coffee?
i, ii , iii, iv
iii, iv, ii, i
iv, i, ii, iii
i, ii, iv, iii

Answer 1

Compute sugar per coffee mass (sugar concentration):
- i: 10 g / 100 g = 0.10 (10%)
- ii: 10 g / 200 g = 0.05 (5%)
- iii: 4 g / 200 g = 0.02 (2%)
- iv: 4 g / 100 g = 0.04 (4%)

From sweetest to least: i, ii, iv, iii.
