The question asks about the basis of Mendeleev's periodic table. To answer this, recall the fundamental principle Mendeleev used to organize the known elements during his time.
D) Increasing atomic mass. Mendeleev's periodic law stated that the properties of elements are a periodic function of their atomic masses. He arranged elements in order of increasing atomic mass, which led to the discovery of periodic trends in their properties.
To find the maximum volume of each container, we need to find the largest number that can divide both the volumes of Oil A and Oil B without leaving a remainder. This is equivalent to finding the Highest Common Factor (HCF) or Greatest Common Divisor (GCD) of the two given volumes.
Correct Option: B) 4
The question asks to identify a farming practice common in Northeast India that also leads to soil erosion. We need to evaluate each option based on its prevalence in the region and its environmental impact, specifically concerning soil erosion.
Correct Option: B) Shifting agriculture
To calculate the percentage change, we need to know the allocation for the Smart Cities Mission in the Revised Estimates (RE) of 2023-24 and the Budget Estimates (BE) of 2024-25. The formula for percentage change is:
\[ \text{Percentage Change} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100 \]Identify the values:
Apply the percentage change formula:
\[ \text{Percentage Change} = \frac{\text{BE 2024-25} - \text{RE 2023-24}}{\text{RE 2023-24}} \times 100 \]Substitute the values:
\[ \text{Percentage Change} = \frac{500 - 1600}{1600} \times 100 \]Calculate the difference:
\[ 500 - 1600 = -1100 \]Perform the division:
\[ \frac{-1100}{1600} = -0.6875 \]Convert to percentage:
\[ -0.6875 \times 100 = -68.75\% \]Round to the nearest whole number or common option:
The closest option to \( -68.75\% \) is \( -70\% \).
C) The calculated percentage change is approximately \( -68.75\% \), which rounds to \( -70\% \). This indicates a significant decrease in allocation.
This problem involves analyzing logical statements and conclusions, a common type of question in competitive exams. We will use Venn diagrams to represent the relationships between the categories (cars, buses, trucks, ships) described in the statements. Then, we will evaluate each conclusion based on these diagrams to determine if it logically follows.
A) Neither conclusion (I) nor (II) follows. As analyzed above, neither of the conclusions can be definitively derived from the given statements.
To solve this problem, we need to track Sunil's movements step-by-step on a 2D plane. We can assign coordinates or simply visualize the path to determine his final position relative to his starting point. Then, we calculate the shortest distance and direction needed to return to the starting point.
Therefore, he should drive 9 km to the east to reach Point A again.
Correct Option: D) 9 km to the east
The question asks to identify a specific folk dance from Bihar that portrays the relationship dynamics, specifically love and quarrel, between a married couple. This requires knowledge of Indian folk dances and their regional origins and themes.
Jat-Jatin is a popular folk dance of Bihar, particularly prevalent in the Mithila and Kosi regions. It is primarily performed by women during monsoon nights and often depicts the love and playful quarrels between a husband (Jat) and wife (Jatin), as well as other social issues like poverty, natural calamities, and the difficulties of married life.
Correct Option: A) Jat-Jatin — This dance perfectly matches the description, being a folk dance from Bihar that portrays the love and quarrel of a married couple.
The problem presents a series of three-letter codes. We need to identify the pattern in the alphabetical positions of the letters within each code and between consecutive codes to find the missing term.
The pattern for the first letter is a subtraction of 4 from the alphabetical position: \(22 - 4 = 18\), \(18 - 4 = 14\), \(14 - 4 = 10\). Following this pattern, the next first letter should be \(10 - 4 = 6\), which corresponds to F.
The pattern for the second letter is a subtraction of 4 from the alphabetical position (considering the alphabet as circular, so Y is 25, then 25-4=21 for U, 21-4=17 for Q). To get from C (3) to Y (25), we can think of it as \(3 - 4 = -1\). In a circular alphabet (A=1, B=2, ..., Z=26), \(-1\) is equivalent to \(26 - 1 = 25\), which is Y. So, the pattern is consistent. Following this, the next second letter should be \(17 - 4 = 13\), which corresponds to M.
The pattern for the third letter is a subtraction of 4 from the alphabetical position. \(10 - 4 = 6\), \(6 - 4 = 2\). For B (2) to X (24), it's \(2 - 4 = -2\). In a circular alphabet, \(-2\) is equivalent to \(26 - 2 = 24\), which is X. So, the pattern is consistent. Following this, the next third letter should be \(24 - 4 = 20\), which corresponds to T.
The next term in the series is formed by combining the identified letters: F, M, T. So, the term is FMT.
Correct Option: C) FMT
This is a logical reasoning problem involving scheduling. We need to arrange the exams for seven people (C, D, E, F, S, T, U) over seven days of a week (Monday to Sunday) based on the given clues. We will build a schedule day by day.
This means T has the exam on Wednesday.
This means D has the exam on Saturday.
Since T is on Wednesday, three people between T and F means F must be on Sunday (Wednesday + 3 days + F = Sunday).
This means U and E must be in consecutive slots (U, E).
Combining clues 4 and 5, we have a sequence: U, E, _, C. The only available consecutive slots for U and E are Monday and Tuesday. So, U is on Monday and E is on Tuesday.
Now, applying "only one person has the exam between E and C": E is on Tuesday, so C must be on Thursday (Tuesday + 1 day + C = Thursday).
The only person left is S, and the only day left is Friday. So, S has the exam on Friday.
From the final schedule, S has the exam on Friday.
Correct Option: D) S
The question asks for the first essential step in holozoic nutrition for complex organisms. Holozoic nutrition involves the ingestion of complex organic food materials, which are then digested, absorbed, and assimilated. We need to identify the very initial action taken by the organism to acquire food.
C) ingestion — Ingestion is the act of taking food into the body, which is the absolute first step for any complex organism that obtains nutrients through holozoic nutrition.
