The question asks about the number of research stations India had established in Antarctica by the end of 2015. This requires knowledge of India's Antarctic research program and the timeline of its stations' establishment and operation.
By the end of 2015, India had established three research stations: Dakshin Gangotri (though decommissioned as a primary research station), Maitri, and Bharati. All three had been established by this time, with Bharati becoming fully operational in 2015.
Correct Option: B) 3
To find the length of the train, we need to understand that when a train crosses a pole, the distance covered by the train is equal to its own length. We are given the speed of the train and the time it takes to cross the pole. We will use the formula: \(\text{Distance} = \text{Speed} \times \text{Time}\).
\[ \text{Speed} = 60 \text{ kmph} \]
To convert kmph to m/s, multiply by \(\frac{5}{18}\):
\[ \text{Speed} = 60 \times \frac{5}{18} \text{ m/s} \]
\[ \text{Speed} = \frac{10 \times 5}{3} \text{ m/s} \]
\[ \text{Speed} = \frac{50}{3} \text{ m/s} \]
\[ \text{Time} = 30 \text{ s} \]
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
\[ \text{Length of train} = \frac{50}{3} \text{ m/s} \times 30 \text{ s} \]
\[ \text{Length of train} = 50 \times 10 \text{ m} \]
\[ \text{Length of train} = 500 \text{ m} \]
Correct Option: C) 500 m
The question asks to identify the Maharaja responsible for building the Jantar Mantar in Delhi. This is a factual question related to Indian history and architecture, specifically focusing on astronomical observatories built in the 18th century.
B) Jai Singh II of Jaipur — Maharaja Sawai Jai Singh II of Jaipur was indeed the builder of the Jantar Mantar in Delhi, as well as four other similar observatories across India. He was a keen astronomer and scholar.
A statement followed by some conclusions are given below.
Statement:
Customer service cannot be enforced. It has to come from within.
Conclusions:
I. Customer service should be voluntary.
II. Employees do not serve customers.
Find which of the given conclusions logically follow from the given statement.
Only conclusion I follows.
Only conclusion II follows.
Both I and II follow.
Neither I nor II follows.
The problem asks us to determine which of the given conclusions logically follow from the provided statement. We need to analyze the statement carefully and check if each conclusion can be directly inferred from it.
A) Only conclusion I follows. This is correct because the statement "Customer service cannot be enforced. It has to come from within" directly implies that customer service must be voluntary. Conclusion II is an unwarranted generalization and does not follow from the statement.
This question tests knowledge about the India State Forest Report (ISFR) 2015, specifically regarding the state with the largest forest cover in terms of area. This requires recalling factual information from the report.
Correct Option: C) Madhya Pradesh had the largest forest cover in terms of area as per the India State Forest Report 2015.
The problem is a simple algebraic equation involving addition and subtraction of decimal numbers. We need to find the missing value by isolating it in the equation.
Correct Option: D) 2.346
A's share is 2 times that of B whose share is 3 times that of C. Rs. 1,800/- is to be given to them in that ratio. B's share is
To find B's share, we first need to establish the ratio of shares for A, B, and C. We are given relationships between A and B, and B and C. We will express all shares in terms of a single variable (C's share in this case) to find the combined ratio. Then, we will divide the total amount (Rs. 1,800) according to this ratio.
Establish the relationship between shares:
Determine the ratio of A : B : C:
From the above, the shares are \(6x\), \(3x\), and \(x\) respectively.
\[ \text{A} : \text{B} : \text{C} = 6x : 3x : x = 6 : 3 : 1 \]Calculate the sum of the ratio parts:
\[ \text{Sum of ratio parts} = 6 + 3 + 1 = 10 \]Calculate B's share:
The total amount to be distributed is Rs. 1,800. B's share is 3 parts out of 10 total parts.
\[ \text{B's share} = \left( \frac{\text{B's ratio part}}{\text{Sum of ratio parts}} \right) \times \text{Total amount} \] \[ \text{B's share} = \left( \frac{3}{10} \right) \times 1800 \] \[ \text{B's share} = 3 \times 180 = 540 \]So, B's share is Rs. 540.
Correct Option: B) Rs. 540
Cell phone : Communication :: Cycle : ?
This is an analogy question where you need to identify the relationship between the first pair of words and then apply the same relationship to the second pair to find the missing word.
Correct Option: D) Transportation. A cycle is a means of transportation, just as a cell phone is a means of communication.
