The question asks to identify the first Vernacular newspaper of India. To answer this, we need to recall the history of early Indian newspapers and distinguish between English and vernacular publications.
Correct Option: A) Samachar Darpan
Samachar Darpan, a Bengali weekly, was published on May 23, 1818, by the Serampore Mission Press. It is historically significant as the first newspaper in an Indian vernacular language.
The question asks for the correct statement about El Niño. We need to evaluate each option based on the established scientific understanding of El Niño.
Correct Option: A) It is unusual warming of surface waters in the Pacific Ocean. This accurately defines El Niño, which is characterized by a significant increase in sea surface temperatures in the central and eastern tropical Pacific Ocean.
The question asks to identify which of the given options is NOT one of the six principal organs of the United Nations. To answer this, one needs to know the list of the six principal organs of the UN.
Correct Option: B) Food and Agriculture Organization of the United Nations
The Food and Agriculture Organization (FAO) is a specialized agency of the United Nations that leads international efforts to defeat hunger. It is an important part of the broader UN system but is not one of the six principal organs established by the UN Charter.
The question asks to identify the gas commonly used in wick-type lighters. This requires knowledge of common fuels used in lighters and their properties.
A) Butane is a highly flammable hydrocarbon gas that is easily liquefied under pressure. It is the most common fuel used in modern gas lighters (which are often confused with wick-type lighters in general usage) and is also a component of petroleum distillates used in wick-type lighters. Its properties make it an excellent choice for portable ignition devices.
To find out when the three shooters will hit their targets together again, we need to find the least common multiple (LCM) of the time intervals at which each shooter hits their target. This LCM will represent the minimum time after which all three events will coincide.
Correct Option: D) 10:01 am
To find the effect on sales, we need to calculate the percentage change in total revenue. Total sales revenue is the product of the price per item and the number of items sold. We will assume initial values for price and quantity, calculate the initial revenue, then calculate the new price and quantity based on the given percentage changes, find the new revenue, and finally determine the percentage change in revenue.
Let the original price of a gun be \(P = 100\) units.
Let the original number of guns sold be \(Q = 100\) units.
Initial Sales Revenue \(= P \times Q\)
\[ \text{Initial Sales Revenue} = 100 \times 100 = 10000 \]The price was increased by 25%.
New Price \(= P + (0.25 \times P)\)
\[ \text{New Price} = 100 + (0.25 \times 100) = 100 + 25 = 125 \]The number of guns sold decreased by 15%.
New Quantity \(= Q - (0.15 \times Q)\)
\[ \text{New Quantity} = 100 - (0.15 \times 100) = 100 - 15 = 85 \]New Sales Revenue \(= \text{New Price} \times \text{New Quantity}\)
\[ \text{New Sales Revenue} = 125 \times 85 \] \[ 125 \times 85 = 10625 \]Percentage Change \[= \frac{\text{New Sales Revenue} - \text{Initial Sales Revenue}}{\text{Initial Sales Revenue}} \times 100\%\]
\[ \text{Percentage Change} = \frac{10625 - 10000}{10000} \times 100\% \] \[ \text{Percentage Change} = \frac{625}{10000} \times 100\% \] \[ \text{Percentage Change} = 0.0625 \times 100\% = 6.25\% \]Since the value is positive, it is an increase.
Alternatively, we can use the percentage change formula for products: If a quantity \(A\) changes by \(x\%\) and another quantity \(B\) changes by \(y\%\), then their product \(A \times B\) changes by approximately \((x + y + \frac{xy}{100})\%\).
Since the result is positive, it is a 6.25% increase.
Correct Option: A) 6.25% increase
This problem can be solved using the concept of work and time. We will calculate the individual work rates of Y and the combined work rate of X and Y. Then, we will subtract Y's work rate from the combined work rate to find X's work rate, which will allow us to determine the time X takes to complete the task alone.
Calculate the combined work rate of X and Y:
If X and Y together can finish a task in 20 days, their combined work rate for one day is:
Calculate the work rate of Y alone:
If Y alone can finish the same task in 25 days, Y's work rate for one day is:
Calculate the work rate of X alone:
The work rate of X alone can be found by subtracting Y's work rate from the combined work rate of X and Y:
Perform the subtraction:
To subtract the fractions, find a common denominator, which is the Least Common Multiple (LCM) of 20 and 25. The LCM of 20 and 25 is 100.
Determine the time X takes to finish the task alone:
If X's work rate is \(\frac{1}{100}\) task per day, then X alone can finish the task in the reciprocal of this rate:
Correct Option: C) 100
Select the Venn diagram that best represents the relationship between the following classes.
Raipur, Chhattisgarh, Bihar
To determine the correct Venn diagram, we need to understand the relationship between Raipur, Chhattisgarh, and Bihar. Raipur is a city within the state of Chhattisgarh, while Bihar is a separate state altogether. This implies a hierarchical relationship between Raipur and Chhattisgarh, but no direct connection between Bihar and these two.
Option C shows a large circle representing Chhattisgarh with a smaller circle inside it representing Raipur, and another separate circle representing Bihar. This accurately reflects the relationship.
Correct Option: C) The diagram correctly shows Raipur as part of Chhattisgarh, with Bihar as a separate entity.
The question asks to identify the Indian state where the classical dance form Kuchipudi originated. This requires knowledge of the origins of various Indian classical dance forms.
Correct Option: B) Andhra Pradesh is the correct answer because Kuchipudi originated in a village of the same name in the state of Andhra Pradesh.
The question asks to identify the company responsible for the Bhopal gas tragedy in 1984, which involved the leakage of Methyl Isocyanate (MIC). This is a direct recall question related to a significant historical industrial disaster in India.
A) Union Carbide — Union Carbide India Limited (UCIL), a subsidiary of the American Union Carbide Corporation, owned and operated the pesticide plant in Bhopal where the catastrophic gas leak of Methyl Isocyanate occurred in December 1984.
