The question asks to identify the singer who holds a Guinness World Record for recording the highest number of songs in several languages. This requires knowledge of prominent Indian singers and their achievements, specifically those recognized by Guinness World Records.
C) P. Susheela β P. Susheela, a legendary Indian playback singer, holds the Guinness World Record for recording the highest number of songs in several languages. As of 2016, she had reportedly sung over 17,695 songs in various Indian languages, a remarkable achievement that earned her this distinction.
The question asks to identify which discipline is NOT included in space research. We need to evaluate each option based on its relevance to the field of space research.
Based on this evaluation, human culture is the discipline least directly involved as a core scientific or technological component of space research.
Correct Option: A) Human culture is not a direct scientific or technological discipline within space research. While space exploration can have cultural impacts or be influenced by cultural factors, the study of human culture itself is not a core component of the scientific and engineering endeavors of space research.A question and three statements labeled (I), (II) and (III) are given. You have to decide which statement(s) is/are sufficient to answer the question.
Question: How many people are in the queue?
Statements:
I. A man is 3rd from the beginning of the queue.
II. A man is 20th from the center of the queue.
III. A man is 7th from the end and 14th from the beginning.
Select the right option from the following.
Only statement II is sufficient.
Only statement I is sufficient.
Data inadequate.
Only statement III is sufficient.
We need to determine which statement or combination of statements provides enough information to calculate the total number of people in the queue. We will analyze each statement individually to see if it leads to a unique solution.
Analyze Statement I: "A man is 3rd from the beginning of the queue."
Analyze Statement II: "A man is 20th from the center of the queue."
Analyze Statement III: "A man is 7th from the end and 14th from the beginning."
Correct Option: D) Only statement III is sufficient.
The question asks to identify where Chlorofluorocarbons (CFCs) are NOT used. CFCs are known for their use as refrigerants, propellants, and in certain types of foam. We need to evaluate each option based on the common applications of CFCs.
Correct Option: B) Mixer and grinders β Mixer and grinders are electrical appliances that operate using motors and do not require refrigerants, propellants, or foam-blowing agents like CFCs for their function.
The problem asks us to complete an analogy. Analogies test our ability to identify the relationship between a given pair of words and then apply the same relationship to another word to find its corresponding pair. The first pair is "Illiterate : Educated". We need to determine the relationship between these two words.
Correct Option: B) Drought is the opposite of a flood, representing a severe lack of water, which directly contrasts with a flood's excess of water.
The question asks to identify the country for which archery is the national sport. This is a factual recall question related to general knowledge about countries and their national sports.
Correct Option: C) Bhutan. Archery is the national sport of Bhutan, an integral part of its cultural and religious festivals.
The question asks for the most appropriate characteristic that defines an 'ethnic' group of people. We need to understand the core concept of ethnicity to choose the best option.
B) shared culture. An ethnic group is fundamentally defined by a common cultural heritage, which includes shared language, traditions, customs, values, and often a sense of common origin or history.
The question asks to identify the incorrect statement among the given options regarding different types of numbers. We need to evaluate each statement based on the definitions and properties of rational, irrational, and real numbers.
A rational number is defined as any number that can be expressed as the quotient or fraction \(p/q\) of two integers, a numerator \(p\) and a non-zero denominator \(q\). Examples include \(1/2\), \(-3/4\), \(5\), etc. Since fractions are precisely numbers expressed in the form \(p/q\), rational numbers inherently include fractions. Therefore, this statement is incorrect.
The set of real numbers (\(\mathbb{R}\)) is composed of two disjoint subsets: rational numbers (\(\mathbb{Q}\)) and irrational numbers (\(\mathbb{I}\)). This means that any real number is either rational or irrational, but not both. If a real number is not rational, by definition, it must be irrational. This statement is correct.
Each real number corresponds to a unique point on the number line, and each point on the number line corresponds to a unique real number. This one-to-one correspondence implies that every real number is distinct and unique. This statement is correct.
The set of real numbers is closed under the operations of addition, subtraction, and multiplication. Division is also possible for any real number by a non-zero real number. These are fundamental properties of real numbers, making them a field in abstract algebra. This statement is correct.
A) Rational numbers do not include fractions.
This statement is incorrect because, by definition, rational numbers are numbers that can be expressed as a fraction \(p/q\), where \(p\) and \(q\) are integers and \(q \neq 0\). Therefore, rational numbers explicitly include fractions.
To answer this question, we need to understand the different categories of software and classify MS Word based on its primary function.
Correct Option: A) Application Software
Arrange the numbers in descending order: 3\(\sqrt{5}\), 2\(\sqrt{8}\), 4\(\sqrt{6}\)
4\(\sqrt{6}\) < 3\(\sqrt{5}\) < 2\(\sqrt{8}\)
2\(\sqrt{8}\) > 4\(\sqrt{6}\) > 3\(\sqrt{5}\)
4\(\sqrt{6}\)> 3\(\sqrt{5}\) > 2\(\sqrt{8}\)
2\(\sqrt{8}\) > 3\(\sqrt{5}\) < 4\(\sqrt{6}\)
To compare numbers involving square roots, it is often easiest to square each number. This eliminates the square root, allowing for a direct comparison of the resulting integers. The order of the squared numbers will be the same as the order of the original positive numbers.
Square the first number: \(3\sqrt{5}\)
\[ (3\sqrt{5})^2 = 3^2 \times (\sqrt{5})^2 = 9 \times 5 = 45 \]
Square the second number: \(2\sqrt{8}\)
\[ (2\sqrt{8})^2 = 2^2 \times (\sqrt{8})^2 = 4 \times 8 = 32 \]
Square the third number: \(4\sqrt{6}\)
\[ (4\sqrt{6})^2 = 4^2 \times (\sqrt{6})^2 = 16 \times 6 = 96 \]
Compare the squared values:
The squared values are 45, 32, and 96.
Arranging these in descending order:
\[ 96 > 45 > 32 \]
Relate back to the original numbers:
Since \(96\) corresponds to \(4\sqrt{6}\), \(45\) corresponds to \(3\sqrt{5}\), and \(32\) corresponds to \(2\sqrt{8}\), the descending order of the original numbers is:
\[ 4\sqrt{6} > 3\sqrt{5} > 2\sqrt{8} \]
Correct Option: C) 4\(\sqrt{6}\)> 3\(\sqrt{5}\) > 2\(\sqrt{8}\)
A) 4\(\sqrt{6}\) < 3\(\sqrt{5}\) < 2\(\sqrt{8}\) β This option presents the numbers in ascending order, which is the opposite of what the question asks for (descending order).
B) 2\(\sqrt{8}\) > 4\(\sqrt{6}\) > 3\(\sqrt{5}\) β This order is incorrect. \(2\sqrt{8}\) is the smallest number, not the largest.
D) 2\(\sqrt{8}\) > 3\(\sqrt{5}\) < 4\(\sqrt{6}\) β This option uses an incorrect combination of inequality signs and also has the numbers in an incorrect order. \(2\sqrt{8}\) is the smallest, not greater than \(3\sqrt{5}\).
