Read the following passage and answer the item that follows. Your answer should be based on the passage only.
In recent years, the demand for skilled professionals in the technology sector has grown exponentially. However, a significant portion of engineering graduates in India lack the necessary technical and soft skills required by the industry. Surveys indicate that nearly 60% of engineering graduates are unemployable due to gaps in their education and training. Many of these graduates come from rural areas and are the first in their families to pursue higher education. While the government has introduced initiatives to improve the quality of technical education, the results have been mixed. Employers often complain that the curriculum in engineering colleges is outdated and does not align with industry needs. Additionally, there is a lack of emphasis on practical training and problem-solving skills.
Based on the above passage, the following assumptions have been made:
1. The primary responsibility for improving the employability of engineering graduates lies with the government rather than educational institutions.
2. A revised curriculum that incorporates industry requirements and focuses on practical skills could significantly enhance the employability of engineering graduates.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
The first assumption puts the entire onus to improve the technical education ecosystem on the Government. However, the Government alone is not responsible for this. The paragraph puts the onus on the Universities also to update the curriculum as per the industry standards. Hence, the 1st assumption is incorrect.
The 2nd assumption is correct as it talks about the revision in the curriculum to make the engineers more employable inline with the industry standards. Hence, the 2nd assumption is correct.
Therefore, (b) is the correct answer.
At what time between 3 O'clock and 4 O'clock will the hand of the clock be together?
(a) 16 (3/11) min past 3
(b) 14 (3/11) min past 3
(c) 13 (2/11) min past 3
(d) 16 (4/11) min past 3
To find out the time at which the hour and the minute hands will be together or, in other words, to find out the time at which the hour and the minute hand will make an angle of 0 degrees, we have to multiply 3 by 60/11.
Multiplying 3 with 60/11 we get 180/11 or 16 (4/11).
It means that at 3:16 (4/11) or 16 (4/11) minutes after 3:00, the minute and the hour hands of the clock will be together making an angle of 0 Degrees.
Therefore, (d) is the correct answer.
Five men and four women are to be seated in a row for a group photograph such that no two women sit together and no two men sit together. Find the number of ways in which this can be arranged.
(a) 2880
(b) 1440
(c) 720
(d) 1
5 men and 4 women are to be seated in such a way that no 2 men are together and no 2 women are together.
Let us say that the arrangement looks like this: M W M W M W M W M
In the above arrangement, we can see that 5 men are to be seated in such a way that no 2 men are together. So, 5 men are to be seated at 5 places so we will use the Permutation here i.e. 5P5 (We have used permutation here because the order of seating is important)
After 5 men are seated M _ M _ M _ M _ M, we have to arrange for women in the 4 spaces between 5 men as shown in the arrangement. So, 4 women can be seated at 4 places in 4P4 ways. (We have used permutation because the order of seating is important)
Total number of ways = 5P5 X 4P4 = 2880 ways.
Therefore, (a) is the correct answer.
A man can row 9 km/h in still water. It takes him twice as long as to row up as to row down. Find the rate of stream of the river.
(a) 3 Km/Hr
(b) 3.5 Km/Hr
(c) 4Km/Hr
(d) 4.5 Km/Hr
Speed of the boat in still water – 9 Km/Hr
Let the speed of the stream be – x Km/Hr
So, the net speed while going up will be – 9-x Km/Hr
The net speed while going down will be – 9+x Km/hr
The question says that the time taken by the boat to go up is twice the time taken by the boat to go down. We can write the same in the form of an equation like: (Time up/Time down = 2/1)
Since, time and speed are inversely proportion to each other, we can rephrase the above equation as follows: (Speed down/Speed up = 2/1)
Putting the values of Speed Up and Speed Down in the above equation we get:
(9+x)/(9-x) = 2/1
Solving the equation we get x = 3 Km/Hr i.e. the speed of the stream is 3 Km/Hr.
Therefore, (a) is the correct answer.
A Question is given followed by two Statements I and II. Consider the Question and the Statements.
A certain amount was distributed among X, Y and Z.
Question: Who received the least amount?
Statement-I: X received 4/5 of what Y and Z together received.
Statement-II: Y received 2/7 of what X and Z together received.
Which one of the following is correct regarding the above Question and the Statements?
(a) The Question can be answered by using one of the Statements alone, but cannot be answered using the other Statement alone
(b) The Question can be answered by using either Statement alone
(c) The Question can be answered by using both the Statements together, but cannot be answered using either statement alone
(d) The Question cannot be answered even by using both Statements together
This is PYQ of UPSC CSE CSAT 2024.
(The question can be answered using both statements together but cannot be answered using either statement alone.)
In such data sufficiency type questions, first, we must consider statement-1 and statement-2 alone. If we are not able to find the answer using the statements alone, we must consider both statements together.
In this above question, let us consider Statement-1 alone first of all. Please note, whenever we are considering Statement-1 alone, we will never consider Statement-2 along with it. (We will act as if Statement-2 is not given altogether).
Considering Statement-1 alone:
From the above equation, we cannot tell who received the least amount. There is no clarity about the exact value of and relation between X, Y, and Z. Hence, Statement-1 alone is not sufficient to answer the question.
Now, let us consider the Statement-2 alone (assuming that Statement-1 does not exist):
Considering Statement-2 alone:
From the above equation, we cannot tell who received the least amount. There is no clarity about the exact value of and relation between X, Y, and Z. Hence, Statement-2 alone is not sufficient to answer the question.
Since, we have been unable to solve the question using both the Statements individually, let us now consider both the Statements together.
Considering both the statements together we get:
Substituting the value of Y in the first equation we get:
The above relation clearly shows that X is greater than Z. Now let us substitute the value of X in the equation above to find the relation between Y and Z.
In this equation, let us substitute the value of X.
The above relation clearly shows that Z is greater than Y.
Combining all the relations derived above, we get X>Z>Y; hence, Y is the smallest number. So, we could find the solution to the question using both Statements.
Therefore, (c) is the correct answer.
