Why is the shortcut necessary for Mixtures and Allegations in exams?
Correct Answer
D. Time management
Explanation
The shortcut for Mixtures and Allegations is necessary in exams because it helps in saving time. This topic involves complex calculations and formulas, which can be time-consuming if solved through traditional methods. By using shortcuts, students can quickly solve these problems and allocate their time effectively to other questions. This ensures that they can complete the exam within the given time frame and maximize their chances of scoring well.
2.
What is the rule for finding the ratio of two or more ingredient at a price?
Correct Answer
B. Alligation
Explanation
Alligation is a rule used to find the ratio of two or more ingredients at a given price. It is commonly used in solving mixture problems. By using alligation, the quantities of the ingredients can be determined based on their prices, allowing for the calculation of the ratio. This rule is particularly useful in various fields such as chemistry, pharmacy, and cooking, where different ingredients need to be combined in specific ratios to achieve desired results.
3.
What is the cost price of unit quantity of a mixture
Correct Answer
D. Mean Price
Explanation
The cost price of a unit quantity of a mixture refers to the average price at which the mixture is acquired. The mean price is the average price of the mixture, which takes into account the prices of all the components in the mixture. Therefore, the mean price is the correct answer as it represents the cost price of the unit quantity of the mixture.
4.
How many component is mixtures divided into?
Correct Answer
C. 2
Explanation
Mixtures are divided into two components.
5.
Which of these alphabets is used in the representation of "Cheaper Price"?
Correct Answer
B. X
Explanation
The alphabet "X" is used in the representation of "Cheaper Price".
6.
Which of these topics support the use of Mixture and Allegations?
Correct Answer
C. Ratio and Proportions
Explanation
Ratio and Proportions support the use of Mixture and Allegations because they involve comparing quantities and finding the ratio between them. Mixture problems often involve combining different substances with known ratios to find the resulting mixture's properties. Similarly, Allegations problems involve comparing the ratios of different components in mixtures to determine the final composition. Therefore, understanding and applying the concepts of ratio and proportions is essential in solving Mixture and Allegations problems.
7.
Which of these units show the need of mixture as a method?
Correct Answer
A. Liter
Explanation
The liter is the unit of measurement for volume, which often involves the need for mixtures. In many scientific experiments or cooking recipes, different substances or ingredients need to be combined in specific ratios to achieve the desired result. Therefore, the liter unit is commonly used to measure liquids that are mixed together.
8.
Which of these subjects work hand in hand with Allegations and Mixtures?
Correct Answer
D. Math
Explanation
Allegations and mixtures involve the combination of different quantities or substances, and math is a subject that deals extensively with calculations and formulas related to mixing and combining quantities. It includes concepts such as ratios, proportions, and percentages, which are essential in solving problems related to allegations and mixtures. Therefore, math works hand in hand with allegations and mixtures.
9.
Which of these types of mixture is formed by the joining of two or more ingredient?
Correct Answer
C. Simple mixtures
Explanation
Simple mixtures are formed by the joining of two or more ingredients. In a simple mixture, the substances that are combined retain their individual properties and can be separated by physical means, such as filtration or evaporation. This is different from compound mixtures, where the substances chemically combine to form a new substance with different properties. Complex mixtures refer to mixtures that contain a large number of different components, while ordinary mixtures is not a specific term used to describe a type of mixture.
10.
Which of these is denoted as M in the Allegation methods?
Correct Answer
B. Mean Value
Explanation
In the Allegation methods, the variable M is denoted as the Mean Value. This means that M represents the average value of a set of data. It is calculated by summing up all the values in the set and dividing it by the total number of values. The Mean Value is commonly used in statistics to measure the central tendency of a dataset and is often used to make comparisons or predictions based on the average value.
