B, C, D, E, F and G are six team members who joined a team on different days of the same month, viz. 2nd, 4th, 5th, 8th, 10th and 11th of January.
C joined on one of the days before F, E and G. B joined immediately before F. D joined immediately before C. E joined on one of the days after B and before G. Who joined the team on 10th of January?
This is a logical reasoning problem involving sequencing. We need to deduce the joining order of six team members (B, C, D, E, F, G) on six specific dates (2nd, 4th, 5th, 8th, 10th, 11th of January) based on the given clues. We will use a table or a linear arrangement to place the members according to the clues.
From D-C and C is before F, E, G, we have D-C- (F, E, G).
From B-F and B < E < G, we have B-F < E < G.
Now combine these. C is before F, E, G. B is immediately before F. E is after B and before G. This implies the sequence B-F-E-G. Since C is before F, E, G, and D is immediately before C, the overall sequence must start with D-C. So, the complete sequence is D-C-B-F-E-G.
The six members are D, C, B, F, E, G.
The six dates are 2nd, 4th, 5th, 8th, 10th, 11th.
Mapping them in order:
A) E is the correct option because, by logically combining all the given clues, the sequence of joining is D, C, B, F, E, G. When mapped to the given dates, E joins on the 10th of January.
The given table shows the number of candidates who appeared for the interview and the number of candidates who got selected for the post of Assistant Professor in XYZ university, from different states over the years. Study the table and answer the question.
| State | Year | |||||
| 2020 | 2021 | 2022 | ||||
| Interviewed | Selected | Interviewed | Selected | Interviewed | Selected | |
| A | 1200 | 800 | 1500 | 700 | 1800 | 1000 |
| B | 1500 | 600 | 1600 | 800 | 2000 | 1120 |
| C | 2000 | 680 | 2200 | 900 | 1800 | 1100 |
| D | 1600 | 700 | 1500 | 950 | 1800 | 1200 |
| E | 1500 | 490 | 1100 | 400 | 1300 | 800 |
In the year 2020, the total number of candidates who got selected from different states is approximately what percentage of the total number of candidates who appeared for the interview from different states in the same year?
To find the percentage of selected candidates out of interviewed candidates in the year 2020, we need to calculate the total number of selected candidates and the total number of interviewed candidates for that year across all states. Then, we will use the formula for percentage: \[\frac{\text{Total Selected}}{\text{Total Interviewed}} \times 100\%\].
B) 41.9% is the closest approximation to the calculated percentage of selected candidates out of interviewed candidates in 2020.
In this question, a group of letters is coded using numbers as per the table given below and the conditions which follow. The correct combination of codes following the conditions is your answer.
| Letter/Symbol | I | M | H | R | D | C | E | V |
| Code | 4 | 8 | 0 | 1 | 3 | 5 | 7 | 9 |
Conditions:
(i) If the first element is a vowel and the last, a consonant, the codes for these two (the first and the last elements) are to be interchanged.
(ii) If the first element is a consonant and the last, an vowel, the first and last elements are to be coded as 2.
(iii) If the middle letter is a vowel, then it is to be coded as 6.
Question: DRIVE
The problem requires us to code the word "DRIVE" based on a given letter-to-number mapping and a set of conditions. We need to apply the conditions sequentially to determine the final code.
D) 21692 is the correct code derived after applying all the given conditions.
The question asks about the essential mineral required for the synthesis of the hormone thyroxin. This is a direct knowledge-based question related to human physiology and nutrition. We need to identify which of the given minerals plays a crucial role in the structure or production of thyroxin.
Therefore, iodine is the mineral required for the formation of thyroxin.
B) Iodine — Iodine is a crucial trace element that is absolutely essential for the synthesis of thyroid hormones, including thyroxin. The thyroid gland actively takes up iodine from the bloodstream to incorporate it into the thyroglobulin protein, which is then processed to form T3 and T4.
The question asks for the amount of energy released when the terminal phosphate bond in ATP (Adenosine Triphosphate) is broken through hydrolysis. This is a fundamental concept in biochemistry, specifically related to energy currency in living organisms.
A) 30.5 kJ/mol. This is the widely accepted standard amount of energy released during the hydrolysis of the terminal phosphate bond of ATP to ADP and inorganic phosphate.
The question asks about the number of stages of life, known as Ashramas, in early Hindu philosophy. This is a direct factual recall question related to ancient Indian social and philosophical structures.
Correct Option: A) Early Hindu philosophy determined four stages of life, known as Ashramas: Brahmacharya, Grihastha, Vanaprastha, and Sannyasa.
The question asks to identify the primary language spoken in the Union Territories of Dadra and Nagar Haveli and Daman and Diu. This requires knowledge of the linguistic demographics of these regions.
A) Gujarati — Gujarati is the most widely spoken language in the Union Territories of Dadra and Nagar Haveli and Daman and Diu, largely due to their geographical proximity to and historical connections with the state of Gujarat. Other languages like Hindi and Marathi are also spoken, but Gujarati is dominant.
This problem requires us to calculate the current flowing through a device given its power consumption and the voltage of the battery it's connected to. We can use the fundamental formula relating power, voltage, and current.
Therefore, the current in the device is 2.5 A.
A) 2.5 A — This is the correct calculation based on the formula \(I = P/V\).
We are given the initial state of a vessel (one-fourth full) and its final state after adding a certain amount of water (three-fourth full). We need to find the total capacity of the vessel. We can set up an equation based on the change in the fraction of the vessel filled, which corresponds to the amount of water added.
Correct Option: A) 20
The question asks about the essential requirement for aerobic respiration. Aerobic respiration is a metabolic process that occurs in the presence of a specific gas to produce energy (ATP) from glucose.
D) oxygen — Aerobic respiration is defined by its requirement for oxygen. Oxygen acts as the final electron acceptor in the electron transport chain, which is a key stage in ATP production during aerobic respiration.
