This is a problem of inequality. We need to analyze the given statement and determine the validity of the two conclusions based on the relationships established between the variables.
The statement is: \(Q \ D > E \geq F\)
This can be broken down into two parts:
Combining these, we have a chain of inequalities: \(Q \ D > E \geq F\). This implies that \(D > E\) and \(E \geq F\). From these, we can infer \(D > F\).
The given statement is \(Q \ D > E \geq F\). There is no information provided about the variable \(C\) in relation to \(F\) or any other variable in the statement. Therefore, we cannot establish a relationship between \(F\) and \(C\).
Thus, Conclusion I (\(F < C\)) cannot be determined as true from the given statement.
The given statement is \(Q \ D > E \geq F\). There is no information provided about the variable \(A\) in relation to \(D\) or any other variable in the statement. Therefore, we cannot establish a relationship between \(D\) and \(A\).
Thus, Conclusion II (\(D < A\)) cannot be determined as true from the given statement.
It seems there might be a typo in the question as presented, or the question implies a different interpretation of the symbols. Let's assume the question intended to present a standard inequality problem where the variables in the conclusions are part of the statement or can be logically derived. Given the options, if neither conclusion is true, then option D would be correct. However, the provided correct answer is B, which states "Only conclusion I is true". This contradicts our analysis if the variables C and A are not part of the original statement.
Let's re-interpret the statement as it is written: "Q D > E ≥ F". If "Q D" is a single entity, say a product or a combined variable, then the analysis remains the same. If the question implies that the letters are individual variables and there's a missing part of the statement, it's problematic.
However, in typical competitive exams, if a variable appears in a conclusion, it must be present or derivable from the statement. Since 'C' and 'A' are not in "Q D > E ≥ F", neither conclusion can be true.
Let's assume there's a typo in the question and the statement should have included C and A, or the conclusions should have used variables from the statement. If we strictly follow the given statement and conclusions, neither is true.
Let's consider a common pattern in such questions: sometimes the letters are just placeholders, and the actual question is about the relationships between the *given* letters in the statement.
If the question intended to ask about relationships between D, E, and F, for example, then:
Let's assume the conclusions were meant to be about D, E, F. For example, if Conclusion I was \(F < D\) and Conclusion II was \(D < E\).
In this hypothetical scenario, only Conclusion I would be true, matching option B. This suggests that the original question might have had a typo in the conclusions, and they were intended to be about D, E, F.
Given the provided correct answer is B, it implies that one of the conclusions *is* true. This can only happen if the variables C and A are somehow linked to the statement, or if the conclusions themselves are typos and should have used D, E, F.
Let's assume the question intended to test the direct relationships from the statement and that the conclusions were meant to be about the variables present.
If we assume a typo in the question and that Conclusion I was meant to be \(F < D\) (which is true from \(D > E \geq F\)) and Conclusion II was meant to be something false, then option B would be correct.
Without further context or clarification, strictly based on "Q D > E ≥ F", neither \(F < C\) nor \(D < A\) can be deduced. However, since a specific answer (B) is given, we must infer that the question expects us to find a true conclusion, possibly by assuming a typo in the conclusion variables.
Let's re-evaluate the possibility of a typo in the question itself. If the statement was, for example, "C > Q D > E ≥ F < A", then we could evaluate. But as it stands, C and A are external.
Considering the possibility of a common mistake or a specific type of question where the letters are just abstract placeholders and the relationships are what matter:
If the question is from a set where the letters in the conclusions are *always* from the statement, then the question as written is flawed. If it's a trick question, then neither is true.
However, if we are forced to choose an option, and the correct answer is B, it implies that Conclusion I is true and Conclusion II is false. This can only be the case if 'C' is implicitly related to 'F' in a way that makes \(F < C\) true, and 'A' is implicitly related to 'D' in a way that makes \(D < A\) false, without any explicit relation given in the statement. This is highly unusual for a well-formed inequality question.
Let's assume the question has a typo and Conclusion I should have been \(F < D\) and Conclusion II should have been \(D < E\).
Under this assumption, only Conclusion I is true, which aligns with option B.
Given the constraints of providing an explanation for a given correct answer, we proceed with the assumption that Conclusion I was intended to be a true statement derivable from the given inequality, and Conclusion II was intended to be a false one. The most direct true statement involving F and another variable from the inequality is \(F < D\).
B) Only conclusion I is true
Assuming a common type of error in competitive exam questions where variables in conclusions might be typos and should refer to variables present in the statement, if Conclusion I was intended to be \(F < D\) (which is derivable from \(D > E \geq F\)), then it would be true. If Conclusion II was intended to be a false statement like \(D < E\), then only Conclusion I would be true. This aligns with the provided answer B.

A trader offers a discount of 10% on an article if a customer makes the payment in cash. How much percentage above the cost price should he mark the article to make a profit of 10%? (Give your answer correct to 2 decimal places.)
To solve this problem, we need to find the marked price (MP) such that after a 10% discount, the trader still makes a 10% profit on the cost price (CP). We can establish relationships between CP, SP (Selling Price), MP, discount, and profit percentage.
Let the Cost Price (CP) of the article be \(₹100\).
The trader wants to make a profit of 10%. So, the Selling Price (SP) should be:
\[ \text{SP} = \text{CP} + (\text{Profit Percentage} \times \text{CP}) = 100 + (0.10 \times 100) = 100 + 10 = ₹110 \]A discount of 10% is offered on the Marked Price (MP). This means the SP is 90% of the MP.
\[ \text{SP} = \text{MP} - (\text{Discount Percentage} \times \text{MP}) = \text{MP} (1 - 0.10) = 0.90 \times \text{MP} \]We know the SP from step 2 is \(₹110\). Now we can find the MP:
\[ 110 = 0.90 \times \text{MP} \] \[ \text{MP} = \frac{110}{0.90} = \frac{1100}{9} \approx ₹122.22 \]The question asks for the percentage above the cost price the article should be marked. This is the difference between MP and CP as a percentage of CP.
\[ \text{Percentage above CP} = \frac{\text{MP} - \text{CP}}{\text{CP}} \times 100 \] \[ \text{Percentage above CP} = \frac{122.22 - 100}{100} \times 100 = \frac{22.22}{100} \times 100 = 22.22\% \]D) 22.22% is the percentage above the cost price the article should be marked to achieve a 10% profit after a 10% discount.
The problem asks us to identify a set of three numbers that follow the same relationship as the given sets: (11, 202, 9) and (13, 233, 8). We need to find a mathematical operation or pattern that connects the first, second, and third numbers in these sets.
Let the numbers be \(A=11\), \(B=202\), and \(C=9\).
We need to find a relationship between \(A\), \(B\), and \(C\). Let's try operations involving squares or multiplication.
Consider the first number \(A\) and the third number \(C\).
If we square the first number: \(A^2 = 11^2 = 121\).
If we square the third number: \(C^2 = 9^2 = 81\).
Let's see if their sum or difference relates to the middle number \(B\).
\(A^2 + C^2 = 121 + 81 = 202\).
This matches the middle number \(B\). So, the relationship is \(A^2 + C^2 = B\).
Let \(A=13\), \(B=233\), and \(C=8\).
Using the derived relationship \(A^2 + C^2 = B\):
\(13^2 + 8^2 = 169 + 64 = 233\).
This also matches the middle number \(B\). The relationship \(A^2 + C^2 = B\) is consistent for both given sets.
B) (15, 274, 7)
The problem states that a large sphere is melted and recast into 1000 identical small spheres. The total volume of the small spheres is equal to the volume of the large sphere. We need to find the diameter of each small sphere. This involves using the formula for the volume of a sphere and equating the total volume.
The volume of a sphere with radius \(r\) is given by:
\[ V = \frac{4}{3} \pi r^3 \]Let \(V_L\) be the volume of the large sphere. Using \(R = 10 \text{ cm}\):
\[ V_L = \frac{4}{3} \pi (10)^3 = \frac{4}{3} \pi (1000) \text{ cm}^3 \]Let \(r\) be the radius of each small sphere. The volume of one small sphere, \(V_S\), is:
\[ V_S = \frac{4}{3} \pi r^3 \]The total volume of 1000 small spheres is \(N \times V_S\). According to the problem statement:
\[ N \times V_S = V_L \]\[ 1000 \times \left(\frac{4}{3} \pi r^3\right) = \frac{4}{3} \pi (1000) \]We can cancel out \(\frac{4}{3} \pi\) and 1000 from both sides:
\[ 1000 r^3 = 1000 \]\[ r^3 = 1 \]\[ r = \sqrt[3]{1} \]\[ r = 1 \text{ cm} \]The diameter \(d\) is twice the radius:
\[ d = 2r \]\[ d = 2 \times 1 \text{ cm} \]\[ d = 2 \text{ cm} \]Correct Option: B) The diameter of each small sphere is 2 cm.
