The question asks to identify which option is NOT part of the "3 R's" of waste management. The 3 R's are a fundamental concept in environmental sustainability, guiding how individuals and organizations can minimize waste and its environmental impact.
Correct Option: B) Refuse — The traditional "3 R's" of waste management are Reduce, Reuse, and Recycle. "Refuse" is a valuable waste management principle but is not part of the original and widely recognized "3 R's" framework.
To solve this problem, we need to first apply the given rules to change each letter in the word CRICKET. Then, we will arrange the newly formed letters in alphabetical order. Finally, we will identify the fifth letter from the right in the alphabetically ordered sequence.
Let's apply these rules to each letter of CRICKET:
The new set of letters formed is B, Q, J, B, J, F, S.
The letters are B, B, F, J, J, Q, S.
Counting from the right:
B) The fifth letter from the right in the alphabetically arranged sequence (B, B, F, J, J, Q, S) is F.
This problem involves finding the ages of two individuals given their age difference and the ratio of their ages. We can represent their ages using a common multiplier based on the given ratio and then use the age difference to find the value of this multiplier.
Correct Option: C) 28 years
Study the following table and answer the question:
| Goods | Profit (in lakhs) | ||
| 2017 | 2019 | 2021 | |
| Refrigerator | 32 | 15 | 43 |
| Fan | 47 | 26 | 54 |
| Television | 28 | 32 | 62 |
| Mobile | 61 | 45 | 47 |
Which goods earned the maximum combined profit in the given three years, and by what percentage is the profit of the highest profitable goods more than the profit of the lowest profitable goods in the year 2019?
The problem requires two main calculations: first, identifying the goods with the maximum combined profit over three years, and second, calculating the percentage by which the profit of the highest profitable goods is more than the profit of the lowest profitable goods in the year 2019.
Comparing the total profits: Refrigerator (90), Fan (127), Television (122), Mobile (153). The maximum combined profit is 153 lakhs, which belongs to Mobile.
The difference in profit is \(45 - 15 = 30\) lakhs.
Percentage increase is calculated as:
\[ \text{Percentage Increase} = \frac{\text{Difference in Profit}}{\text{Lowest Profit}} \times 100 \]\[ \text{Percentage Increase} = \frac{30}{15} \times 100 \]\[ \text{Percentage Increase} = 2 \times 100 \]\[ \text{Percentage Increase} = 200\% \]A) Mobile, 200%
Based on our calculations, Mobile earned the maximum combined profit, and its profit in 2019 is 200% more than the lowest profitable goods (Refrigerator) in 2019.
To identify which compound belongs to the homologous series of alkenes, we need to recall the general formula for alkenes and then check which option fits this formula. We also need to know the general formulas for alkanes and alkynes to differentiate them.
D) C₁₀H₂₀ — This compound has 10 carbon atoms. According to the general formula for alkenes, \( \text{C}_n\text{H}_{2n} \), if \( n=10 \), then the number of hydrogen atoms should be \( 2 \times 10 = 20 \). Since the given formula is \( \text{C}_{10}\text{H}_{20} \), it perfectly matches the general formula for alkenes.
The question asks to identify the initiative of the Ministry of Minority Affairs that received the India International Trade Fair (IITF) 2021 Silver Medal for its commitment to 'Vocal for Local'. This requires knowledge of government schemes and their recognition.
C) Hunar Haat — Hunar Haat is a flagship initiative of the Ministry of Minority Affairs that aims to provide market exposure and employment opportunities to artisans and craftspersons from minority communities. It strongly promotes indigenous products, thereby aligning perfectly with the 'Vocal for Local' campaign. It was indeed awarded the Silver Medal at the India International Trade Fair 2021 for this contribution.
This problem can be solved using a system of linear equations. We are given the total amount withdrawn and the total number of notes of two different denominations. We need to find the number of notes of one specific denomination.
Correct Option: A) 24
The reactivity of metals is determined by their tendency to lose electrons and form positive ions. This tendency is generally summarized in the reactivity series (also known as the activity series) of metals. Metals higher in the series are more reactive than those lower down.
C) Ca > Al > Cu > Hg is the correct decreasing order of reactivity for the given metals, matching the established reactivity series.
The question asks to identify a festival celebrated in West Bengal, Assam, and other Indian states, which coincides with Holi in March. We need to evaluate each option based on its regional celebration and timing.
C) Doljatra is the festival celebrated in West Bengal, Assam, and other states, and it coincides with Holi in the month of March. It is often referred to as the Holi of Eastern India.
In this question, a group of letters is coded using symbols as per the table given below and the conditions which follow. The correct combination of codes following the conditions is your answer.
| Letters | G | T | Y | H | O | R | P | I | C |
| Codes | @ | > | ^ | % | = | # | $ | + | < |
Conditions:
If both the first and the last letters of the word are vowels, then both these letters will be coded as ‘&’.
If both the first and the last letters of the word are consonants, then both these letters will be coded as ‘*’.
What will be the code for the word "COPYRIGHT"?
* = $ ^ # + @ % *
< = $ ^ # + @ % >
= $ ^ # + @ % >
< = $ ^ # + @ % *
The problem requires us to code the word "COPYRIGHT" based on a given letter-to-symbol mapping table and two conditional rules. We need to first identify the individual codes for each letter and then apply the conditions based on whether the first and last letters are vowels or consonants.
Correct Option: A) * = $ ^ # + @ % * This option correctly applies the condition for both first and last letters being consonants and uses the correct codes for the letters in between.
