A mixture of alcohol and water contains 35% alcohol by weight. if 25 g water is added to such a mixture of 100 g, then the percentage of alcohol in the mixture is

Correct Option: 2
Initial mixture (100g):\newline- Alcohol = 35% of 100g = 35g\newline- Water = 65% of 100g = 65g
After adding 25g water:\newline- Total water = 65g + 25g = 90g\newline- Total alcohol = 35g (unchanged)\newline- New total weight = 125g
New percentage of alcohol:\newline35125×100=28%\frac{35}{125} × 100 = 28\%
Therefore, the new percentage of alcohol in the mixture is 28%
