question
A chemist has three bottles, each containing a mixture of acid and water:
- bottle A contains
$40 \mathrm{~g}$ of which is acid,
- bottle B contains $50 \mathrm{~g}$ of which is acid, and
- bottle C contains $50 \mathrm{~g}$ of which is acid.
She uses some of the mixture from each of the bottles to create a mixture with mass $60 \mathrm{~g}$ of which is acid. Then she mixes the remaining contents of the bottles to create a new mixture. What percentage of the new mixture is acid?Plain-text mathematical notation (without MathML)
A chemist has three bottles, each containing a mixture of acid and water:
- bottle A contains $40 \mathrm{~g}$ of which 10% is acid,
- bottle B contains $50 \mathrm{~g}$ of which 20% is acid, and
- bottle C contains $50 \mathrm{~g}$ of which 30% is acid.
She uses some of the mixture from each of the bottles to create a mixture with mass $60 \mathrm{~g}$ of which 25% is acid. Then she mixes the remaining contents of the bottles to create a new mixture. What percentage of the new mixture is acid?Original LaTeX notation
A chemist has three bottles, each containing a mixture of acid and water:
- bottle A contains $40 \mathrm{~g}$ of which $10 \%$ is acid,
- bottle B contains $50 \mathrm{~g}$ of which $20 \%$ is acid, and
- bottle C contains $50 \mathrm{~g}$ of which $30 \%$ is acid.
She uses some of the mixture from each of the bottles to create a mixture with mass $60 \mathrm{~g}$ of which $25 \%$ is acid. Then she mixes the remaining contents of the bottles to create a new mixture. What percentage of the new mixture is acid?question type
