In the realm of competitive exams, there’s a topic that stands apart in its approach and uniqueness: Data Sufficiency Questions. If you’re aiming for success in exams such as IBPS Clerk, IBPS RRB Clerk/PO, SBI Clerk/PO, or others, you’ll inevitably come across Data Sufficiency Questions. Why are these questions crucial? Because they are not just about solving mathematical problems; they are about discerning whether you have enough information to solve them.
At its core, data sufficiency is an intriguing area of quantitative aptitude. Unlike other sections where you’re required to crunch numbers till you get an answer, data sufficiency questions challenge you in a different manner. The essence of these questions is captured in the name itself. Your task isn’t necessarily to find the exact answer but to determine if the provided data is sufficient to get to that answer.
The charm of Data Sufficiency Questions lies in their inherent challenge: they ask you not to complete the puzzle but to identify if you have all the pieces. This is why understanding the structure and approach to these questions is crucial. And for those who may wonder about data sufficiency meaning in Hindi, it’s all about understanding if you have the requisite data to address a question.
Data Sufficiency meaning in Hindi : आपको यह निर्णय करना है कि कथन में दी जा रही सामग्री उत्तर देने के लिए पर्याप्त है या नहीं. आपको डाटा और अपने गणितीय ज्ञान का प्रयोग कर संभावित उत्तरों में से चुनाव करना है
If you’ve ever encountered data sufficiency problems, you’ll appreciate the twist they bring to the table. You’re presented with a question, followed typically by two or three statements. Your task? Decide which of these statements, alone or in combination, offer enough data to answer the main question. This unique format is what makes data sufficiency questions a favorite among exam setters and a challenge for aspirants.
For many, the allure of Data Sufficiency Questions is the fact that you don’t always have to solve the entire problem. As mentioned, the goal is to gauge whether the data is sufficient. This means you might not need to go through the whole calculation process, a fact that can be a real time-saver during exams. Especially when dealing with data sufficiency aptitude tests, where speed and accuracy are of the essence.
Another integral part of Data Sufficiency Questions are the options provided. Understanding data sufficiency options is crucial because they often guide your approach to the question. Are you using one statement, two, or perhaps both? These options help you structure your thought process.
For those who are more comfortable with Hindi, we’ve also catered to your needs with data sufficiency questions in Hindi. Because language should never be a barrier to understanding and mastering crucial concepts.
To sum up, Data Sufficiency Questions are not just another topic in the world of competitive exams. They are a testament to the evolving nature of these tests and the importance of not just knowing but understanding. As we delve deeper into this topic, remember, it’s not always about the answer but about the journey to determine if you can reach that answer.

C. The data either in statement I alone or in statement II alone is sufficient to answer the question
D. The data given in both statements I and II together are not sufficient to answer the question
E. The data given in both statements I and II together are necessary to answer the question.
Option “E” is correct.
Answer: E
From Statement I:
There are 25% women and 35% children passengers,
So, the remaining passengers = 100% – (25% + 35%) = 100% – 60% = 40%
So, the men in the bus = 40%
Statement II: There are 148 men passengers are there in the bus.
From Statement I and II:
Let x be the total number of passengers in the bus.
Number of men in the bus = 148
So, according to the question,
= 40/100 × x = 148
= x = 148 × 100/40 = 370
So, the total number of people = 370
Hence, Statement I and Statement II both are necessary to answer the question.

E. The data given in both statements I and II together are necessary to answer the question.
Option “C” is correct.
Answer: C
From Statement I:
Let cost of 1 ticket = Rs. x
So, total number of students who got tickets = 60000/x
So, according to the question,
(x – 50) × 60000/x = 60000 – 15000
Solving we get x = Rs. 200
So, the cost of 1 ticket = Rs. 200
From Statement II:
(x + 50) × 60000/x = 125/100 × 60000
Solving we get, x = Rs. 200
So, the cost of 1 ticket = Rs. 200.
Hence, Either Statement I alone or Statement II alone is sufficient to answer the question.

CP of the article = 5x
MP of the article = 6x
Profit = Rs.80
So, Statement II alone is not sufficient to answer the question.
From statement I and II,
6x * 85/100 = 5x + 80
5.1x – 5x = 80
0.1x = 80
x = 800
SP of the article = 5 * 800 + 80 = Rs.4080
Both statements are necessary to answer the question.

From statement I,
B + C = 7/120
A + B = 1/24
So, Statement I alone is not sufficient to answer the question.
From statement II,
A + B + C = 3/40
Efficiency of A and B = 100:150 = 2:3
Time ratio of A and B = 3:2
Efficiency of B and C = 75:100 = 3:4
Time ratio of B and C = 4:3
Time ratio of A, B and C = 6:4:3
1/6x + 1/4x + 1/3x = 3/40
(2 + 3 + 4) /12x = 3/40
x = 10
Pipe A alone fill the tank = 6 * 10 = 60 hours
Pipe C alone fill the tank = 3 * 10 = 30 hours
A + C = 1/60 + 1/30 = 1/20
So, Statement II alone is sufficient to answer the question.

Answer: E
From statement I,
(A + 6)/(B + 6) = 15/13
So, Statement I alone is not sufficient to answer the question.
From statement II,
(A – 4)/(B – 4) = 125/100
A’s age 4 years ago = 5x
B’s age 4 years ago = 4x
So, Statement II alone is not sufficient to answer the question.
From statement I and II,
A’s age 6 years after = 5x + 4 + 6 = 5x + 10
B’s age 6 years after = 4x + 4 + 6 = 4x + 10
(4x + 10)/(5x + 10) = 13/15
65x + 130 = 60x + 150
5x = 20
x = 4 years
A’s present age = 5 * 4 + 4 = 24 years
