This question tests knowledge about the themes of recent and upcoming World Expos. To answer correctly, one needs to recall the specific theme associated with Expo 2025 in Osaka, Japan.
Correct Option: B) Designing Future Society for Our Lives
The question asks to identify the region in India that is NOT suitable for tube-well irrigation due to non-alluvial tracts. Tube-well irrigation is most effective in regions with soft, permeable, alluvial soils and a high water table. We need to evaluate each option based on its geological characteristics and suitability for tube-well irrigation.
Correct Option: A) Plateau regions
The question asks for the command that duplicates selected text and places the copy elsewhere. This is a fundamental text editing operation. We need to identify the specific command combination that achieves duplication without removing the original text.
Correct Option: A) Copy and Paste
This combination is precisely designed to duplicate content from one location to another without altering the original source.
The problem asks us to identify the pattern in two given triads of letter pairs and then select an option that follows the same pattern. We need to analyze the positional values of the letters in the English alphabet.
The pattern is: first letter \((+2)\), second letter \((+2)\) for the first transition, and first letter \((+2)\), second letter \((+9)\) for the second transition.
Both triads follow the same pattern: \((+2, +2)\) for the first transition and \((+2, +9)\) for the second transition.
This matches the first transition \((+2, +2)\).
This matches the second transition \((+2, +9)\).
Therefore, option D follows the established pattern.
Correct Option: D) GB-ID-KM
The question asks about the primary role of the Gram Panchayat within India's Panchayati Raj System. To answer this, one must understand the fundamental structure and purpose of local self-government bodies in rural areas as established by constitutional amendments, particularly the 73rd Amendment.
Correct Option: D) To serve as the executive body of village self-government
Kavish ranked 38th from the top and 15th from the bottom in his class. How many students are there in his class?
To find the total number of students in the class, we can use the formula that relates a person's rank from both the top and the bottom of a sequence. When a person's rank from both ends is known, the total number of people can be calculated by adding the two ranks and subtracting 1 (because the person themselves is counted twice).
Thus, there are 52 students in the class.
B) 52 — This is the correct number of students obtained by adding Kavish's rank from the top and bottom and then subtracting 1 to account for Kavish being counted twice.
Simplify: 81 + \( \frac{76}{2} \) + 42 − 86
To simplify the given expression, we need to follow the order of operations, often remembered by the acronym PEMDAS/BODMAS (Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). In this expression, we have division, addition, and subtraction. We will perform division first, then addition and subtraction from left to right.
The given expression is:
\[ 81 + \frac{76}{2} + 42 - 86 \]First, perform the division operation:
\[ \frac{76}{2} = 38 \]Substitute this value back into the expression:
\[ 81 + 38 + 42 - 86 \]Now, perform the addition operations from left to right:
\[ 81 + 38 = 119 \]Continue with the next addition:
\[ 119 + 42 = 161 \]Finally, perform the subtraction:
\[ 161 - 86 = 75 \]Thus, the simplified value of the expression is 75.
C) 75 — As calculated in the step-by-step explanation, following the order of operations leads to the result of 75.
The question states that Vijay's salary was first reduced by 16% and then increased by 11%. We need to calculate the final salary after both successive percentage changes and determine the overall percentage decrease compared to the initial salary.
Identify the given information:
For easier calculation, assume Vijay's initial salary is ₹100.
Calculate the salary after a 16% reduction:
The salary is first reduced by 16%.
\[ \text{Reduction}=\frac{16}{100}\times100 \] \[ =16 \]Therefore, the salary after the reduction is:
\[ 100-16=84 \]The reduced salary is ₹84.
Calculate the salary after an 11% increase:
The salary is subsequently increased by 11%.
This increase is calculated on the reduced salary of ₹84, not on the original salary of ₹100.
\[ \text{Increase}=\frac{11}{100}\times84 \] \[ =9.24 \]Therefore, the final salary is:
\[ 84+9.24=93.24 \]The final salary is ₹93.24.
Calculate the overall decrease:
Compare the final salary with the initial salary:
\[ \text{Decrease}=100-93.24 \] \[ =6.76 \]Therefore, the salary decreased by ₹6.76 for every ₹100 of the initial salary.
Calculate the percentage decrease:
Using the formula:
\[ \text{Decrease Percentage}= \frac{\text{Decrease}}{\text{Initial Salary}}\times100 \]Substituting the values:
\[ =\frac{6.76}{100}\times100 \] \[ =6.76\% \]Therefore, Vijay's final salary is 6.76% lower than his initial salary.
Correct Option: A) 6.76% — Assuming the initial salary is ₹100, a 16% reduction decreases it to ₹84. An 11% increase on ₹84 raises it to ₹93.24. Therefore, the overall percentage decrease is:
\[ \frac{100-93.24}{100}\times100=6.76\% \]
Hence, Option A is the correct answer.
B) 16%: This is incorrect because 16% represents only the initial salary reduction and does not account for the subsequent 11% increase.
C) 1.76%: This is incorrect because the actual decrease after applying both successive percentage changes is 6.76%, not 1.76%.
D) 11%: This is incorrect because 11% represents the subsequent increase on the reduced salary, not the overall percentage decrease from the initial salary.
The question asks to identify the modern-day region corresponding to 'Tirabhukti' as mentioned in Gupta inscriptions. This requires knowledge of historical geography and the administrative divisions of the Gupta Empire.
Correct Option: B) Bihar. 'Tirabhukti' was a province during the Gupta period, and it corresponds to the Tirhut region in present-day Bihar. This region was strategically important and well-documented in Gupta inscriptions.
