Question

One litre of water is mixed with 3 litres of sugar solution containing 4% of sugar. What is the % of sugar in the solution?

• A. 4 %
• B. 3 %
• C. 6 %
• D. None

Answer 1

The correct option is B 3 %

3 L solution contains 4% of sugar

Volume of sugar = $3\times \frac{4}{100}=0.12$ L

Volume of Water in 3 L solution $=3-0.12=2.88$

After adding 1 L of water total amount of water $=1+2.88=3.88$

New % of sugar $=\frac{0.12}{3.88}\times 100=3.09\%$ which is approximately $3\%$.
