West Bengal shares boundaries with _____ countries.
To answer this question, one needs to recall the geographical boundaries of the Indian state of West Bengal and identify the international borders it shares with neighboring countries. A mental map or actual map of India would be helpful.
Correct Option: D) 3
West Bengal shares its international borders with three countries: Bangladesh to the east, Nepal to the north, and Bhutan to the northeast. This makes option D the correct answer.
In the given table, each number is coded as letters following a fixed pattern. In which column does the code NOT follow the pattern?
| A | B | C | D |
| 1595 | 1425 | 1725 | 1325 |
| AEIF | ADBE | AGBE | ACBE |
The problem asks us to identify which column's code does NOT follow a fixed pattern. We need to find the pattern by analyzing the given number-to-letter codes in the columns that do follow the pattern.
C) A
The pattern observed is: The first digit '1' is coded as 'A'. The subsequent digits are coded by their corresponding letter in the English alphabet (e.g., 2 is B, 3 is C, 4 is D, 5 is E, 7 is G, 9 is I). Let's apply this pattern:
Since Column A is the only one that deviates from the established pattern, it is the correct answer.
To calculate the work done, we need to use the formula that relates force, distance, and work. Work done is defined as the product of the force applied and the distance moved in the direction of the force.
Work done (\(W\)) is given by the formula:
\[ W = F \times d \]where \(F\) is the force applied and \(d\) is the distance over which the force is applied in the direction of motion.
The unit of work done is Joules (J).
Correct Option: D) 500 J
This problem involves work and time. We need to calculate the individual work rates of A and B, and then use these rates to determine how many days A worked and subsequently, how many days before the completion of the task A left.
A alone can complete the work in 2.625 days.
\[ \text{A's work rate} = \frac{1}{\text{Time taken by A}} = \frac{1}{2.625} \text{ units/day} \]A and B together can complete the task in 1.5 days.
\[ \text{Combined work rate (A+B)} = \frac{1}{\text{Time taken by A and B together}} = \frac{1}{1.5} \text{ units/day} \]B's work rate is the combined work rate minus A's work rate.
\[ \text{B's work rate} = \text{Combined work rate} - \text{A's work rate} \]\[ \text{B's work rate} = \frac{1}{1.5} - \frac{1}{2.625} \]\[ \text{B's work rate} = \frac{1}{1.5} - \frac{1}{21/8} = \frac{1}{1.5} - \frac{8}{21} \]\[ \text{B's work rate} = \frac{1}{3/2} - \frac{8}{21} = \frac{2}{3} - \frac{8}{21} \]\[ \text{B's work rate} = \frac{14}{21} - \frac{8}{21} = \frac{6}{21} = \frac{2}{7} \text{ units/day} \]Let \(x\) be the number of days A worked. The total time taken to complete the task was 2 days. This means B worked for the entire 2 days.
Total work done = (A's work rate \(\times\) days A worked) + (B's work rate \(\times\) days B worked)
Since the total work is 1 unit (representing the completion of the task):
\[ 1 = \left(\frac{1}{2.625} \times x\right) + \left(\frac{2}{7} \times 2\right) \]\[ 1 = \left(\frac{8}{21} \times x\right) + \frac{4}{7} \]A worked for 1.125 days. The total task took 2 days. A left before the work was completed.
Days before the work getting over that A left = Total time taken - Days A worked
\[ \text{Days A left before completion} = 2 - 1.125 \]\[ \text{Days A left before completion} = 0.875 \text{ days} \]Correct Option: D) 0.875
The question asks to identify the type of tissue found beneath the skin and surrounding internal organs. This points to a tissue that provides insulation, energy storage, and protection. We need to recall the primary functions and locations of the different tissue types listed in the options.
Correct Option: D) Adipose tissue is a type of loose connective tissue that stores fat. It is found beneath the skin, around internal organs, and in other areas of the body. Its primary functions include energy storage, insulation against heat loss, and cushioning/protection of organs.
The problem is a coding-decoding question. We need to identify the pattern used to code "MEAT" as "135120" and then apply the same pattern to code "ZEBRA". The most common pattern in such questions involves assigning numerical positions to letters of the alphabet.
A) 2652181 is the correct code for ZEBRA, as derived by concatenating the alphabetical positions of its letters.
The question asks to identify the host of the Hindi version of "Bigg Boss-11". This is a general knowledge question related to Indian television and popular culture. Recalling the hosts of different seasons of the show is key.
Correct Option: B) Salman Khan was the host for the Hindi version of "Bigg Boss-11". He has been the host for many seasons of the show, including season 11 which aired in 2017.
The question asks for the specific property that describes an atom's ability to attract electrons within a molecule, specifically mentioning halogen atoms. We need to identify the correct chemical term among the given options.
Correct Option: D) Electronegativity is the property of attracting electrons by the halogen atoms in a molecule. Halogens are highly electronegative elements, meaning they have a strong tendency to attract electrons towards themselves when forming chemical bonds.
The question asks for the location of the headquarters of the Board of Control for Cricket in India (BCCI). This is a factual question requiring knowledge of the administrative structure of Indian cricket.
Correct Option: B) Mumbai is the correct answer because the headquarters of the BCCI is located in Mumbai.
The question asks to identify which inert gas belongs to Period 4 of the periodic table. To answer this, we need to recall the positions of inert gases (Group 18 elements) in the periodic table and their corresponding periods.
Correct Option: A) Kr is the inert gas found in Period 4 of the periodic table.
