Question

25% of 250g sugar solution & 40% of 500g sugar solution are mixed then find out the mass percentage in the solution.

Answer 1

Given:
First solution: 25% of 250 g
Second solution: 40% of 500 g

Step 1: Find amount of sugar in each solution
First solution sugar = 25% of 250 = 62.5 g
Second solution sugar = 40% of 500 = 200 g

Step 2: Total sugar
Total sugar = 62.5 + 200 = 262.5 g

Step 3: Total solution mass
Total mass = 250 + 500 = 750 g

Step 4: Mass percentage
Mass % = (262.5 / 750) × 100 = 35%

Final Answer: 35%
