Final answer:
To find the percentage of sugar in the syrup, add the masses of sugar and water together and divide the mass of sugar by the total mass of the solution, then multiply by 100 to get the percentage.
Step-by-step explanation:
To find the percentage of sugar in the syrup, you need to calculate the mass of sugar and water in the solution. In this case, the syrup is made of 10 kg of water and 4 kg of sugar.
First, add the masses of sugar and water together: 10 kg + 4 kg = 14 kg
Now, calculate the percentage of sugar in the solution: (4 kg / 14 kg) * 100% = 28.57%
