Part A (Quantitative Aptitude)
CAT entrance exam question papers with answers:
Ans1: (c)
To find the maximum value of ‘n’, we have to count the number of 7s in 138!
So, n = [138/7] + [138/49], where [x] = maximum integer function
So, n = 19 + 2 =21
Ans 2: (b)
Do Prime factorization of 1430
i.e. 1430 = 13 x 11 x 5 x 2
n! must be 13 or greater since before 13, n! do not contain any 13.
So, the answer must be n = 13 (13! Will contain at least one 5, one 2, one 11 and one 13)
Ans 3: (a)
When 54 i.e. 625 divided by 626, the remainder is -1.
591 = (54x22) x53 = (62522) x125
Rem (591/626) = Rem {(62522) x125/ 626} = Rem {(-1)22 x125/626} = 125
Ans 4: (c)
2n has 8 factors. So, 2n must be of the form of one of the following:
2n = axbxc (no of factors = 2x2x2 = 8, here a, b and c are prime numbers)
Or
2n = axb3 (no of factors = 2x4 = 8, here a and b are prime numbers)
It is clear from here a= 2.
3n has 6 factors. So, 3n must be of the form of one of the following:
3n = b5 (no of factors = (5+1) = 6, where b is a prime numbers)
Or
3n = cxb2 (no of factors = 2x3 = 6, here c and b are prime numbers)
It is clear from here b = 3.
Here c will be a prime number other than 2 and 3.
Case 1:
2n = ax b3= 2n = 2x33; both cases of 3n will not be possible. So 2n cannot be ax b3.
Case 2:
2n = axbxc = 2x3xc; 3n = cxb2 = cx32 is possible
So, n = 3xc
6n = 2x32×c
No of factors = (1+1) x (2+1) x (1+1) = 2x3x2 = 12
Ans 5: 10 possible pairs are there.
Solution is as follows:
Let x = h x a; y = h x b, where h is HCF of x and y; a and b are co-primes
LCM = h x a x b
ATQ
h x a x b – h = 42
h (a x b - 1) = 42
H | (a x b - 1) | a x b | Possibility of a and b |
1 | 42 | 43 | (1, 43) |
2 | 21 | 22 | (1, 22), (2, 11) |
3 | 14 | 15 | (1, 15), (3, 5) |
6 | 7 | 8 | (1, 8) |
7 | 6 | 7 | (1, 7) |
14 | 3 | 4 | (1, 4) |
21 | 2 | 3 | (1, 3) |
42 | 1 | 2 | (1, 2) |
Total possible pairs in a and b are 10.
Therefore, 10 pairs in x and y exist.
Ans 6: (d)
Take the HCF of the number of pairs of shoes and divide the total number of pair of shoes by HCF to find the minimum number of boxes required.
HCF (16, 64, 48, 88, 92, 60, 120, 44) = 4
Number of boxes are required = (16+64+48+88+92+60+120+44)/4 = 133
Since n is even, unit digit of 42n + 1 = 4 (Since 4^odd is always gives 4 as unit digit)
and unit digit of 4n = 6 (Since 4odd is always gives 6 as unit digit)
Ans 7: (c)
Price is increased by 30% means, if initial price was Rs 10 then new price will be Rs. 13
E2 (New Expenditure) = E1 (old Expenditure)
Using,
E2/E1 = (New Price/ Old Price) x (New Consumption/ Old Consumption)
1 = 13/10 x(New Consumption/ Old Consumption)
So, (New Consumption/ Old Consumption) = 10/13
We can say consumption will reduce from 13 to 10 i.e. 23.07%
Ans 8: (b)
Let there are 100x and 100y men and women respectively (Age more than 18 yrs)
Married Men = Married Women
i.e. 36x = 45y
So, x = 5y/4
Total Men = 100x = 100x5y/4 = 125y
Total Population (more than 18yrs) = 125y + 100y = 225y
Men = 125y × 100/225y % = 55.55%.
Ans 9: (d)
Cost of AC-III berth = Rs 2000
Cost of AC-II berth = Rs 2400
Cost of AC-I berth = Rs 2880
Maximum revenue is when all the berths are filled
Revenue from AC-III Coaches = 3x64x2000 = Rs 384000
Revenue from AC-II Coaches = 6x45x2400 = Rs 648000
Revenue from AC-I Coaches = 4x24x2880 = Rs 276480
Total revenue = Rs 384000 + Rs 648000 + Rs 276480 = Rs 1308480
Ans 10: (b)
Revenue from AC-I coaches = Rs 276480
Total Revenue = Rs. 1308480
Share of AC-I = 276480 × 100/1308480 = 21.13%
Direction (Q1-Q3):
The graph below informs about the total area and the population density for 8 different countries. The area of all countries is the same for the two years 2002 and 2008 and is shown by the bar graph, read off from the right-hand Y-axis. The population density is dividing the total population of the country by the area and is depicted by the line graphs and is read off the left-hand Y-axis. The two line graphs refer to the population density in the years 2002 and 2008.
Q1. How many countries had a higher population in 2008 as compared to 2002?

Q3. The country with the largest population in 2008 among the given countries is
A
E
F
Cannot be determined
Population Density = \text {$\frac{Population}{Area}$}
Thus, the Population of a country can be found by multiplying the population density by the area.
CAT Practice Papers: Answers And Solutions
Part B (LRDI)
1. c
Since for all countries, the area remains the same over the two years, 2002 and 2008, then if population density has increased from 2002 to 2008, the population has increased and if population density has decreased, then the population has decreased. The number of countries having a population density in 2008 more than that in 2002 is 6 (except B and E)
2. a
The increase in the population of F = (70 – 62) × 680,000 i.e. 8 × 680,000 = 5,440,000 i.e. 5.44 mn.
3. b
Since the area has remained the same in 2002 and 2008, the percentage increase in the population is the same as the percentage increase in the population density. Thus, the required percentage growth is percentage growth from 46 to 56 i.e. a decrease of 10/46 i.e., 10/46 x100 = 21.73%
The country with the largest population is going to be one that has a higher population density as well as a higher area. Looking for this combination in the graph, the choices are narrowed down to E and F. (Each of the rest of the countries has both the area and the population density lower than one of these two countries)
Population of E in 2008 = 76 × 600 = 45600 thousand.
Population of F in 2008 = 70 × 680 = 47600 thousand.
Thus, in 2008, the highest population is F.
Directions for questions 4 to 7: Answer the questions on the basis of the information given below.

CAT Practice Papers: Answers And Solutions
Solutions:
Since , and we are given Production and Yield figures, so re-arranging the relation to get area, we have
. With the units given, we will get the area in million hectares.
4. c
Just check the table where the yield in second row is more then the yield in the first row in 2008
We see that for Rice, Maize and Pulses, the yield in Summer is more than the yield in Winter.
5. b
The area under cultivation of rice in Winter season in successive years can be found as . And we have to find in which year the growth rate is the greatest. Just by solving the above fraction, we found that in 2008 we have the highest growth rate
6. a
I. Area = = 4.46
II. Area = =6.4
III. Area = =10.51
Thus, increasing order will be I, II, III
7. a

Hello
If you are aiming for the CAT exam this year and considering joining the fourth year, it might be a good idea if you are confident in managing both your academic workload and CAT preparation .
However, the CAT exam is competitive and balancing your BCom studies and preparation might be challenging.
If you think you can handle the extra year and need more time for focused preparation , joining the fourth year could provide that but you should also evaluate your current academic commitments and your ability to stay consistent with CAT preparation .
Hope this gives you the clarity you need.
Hello,
Securing a seat in a National Institute of Technology (NIT) with a JEE Main score of 67 as an SC category candidate is challenging. Consider the following points:
Qualifying Cutoff : The expected qualifying cutoff for SC candidates in JEE Main 2025 is around 65 marks.
Admission Prospects : While you may qualify for JEE Advanced, admission to NITs typically requires higher scores. For instance, in previous years, SC candidates needed higher marks to secure seats in NITs.
Improvement Opportunity : Consider preparing for the next JEE Main attempt to achieve a higher score, thereby enhancing admission prospects in subsequent counseling rounds.
You can also use the JEE Mains College Predictor Tool to predict which college you can get based on your score.
Hope you find it useful!

Hello,
According to the NIFT 2025 exam schedule , the General Ability Test (GAT) is from 9:00 AM to 11:00 AM, and the Creative Ability Test (CAT) is from 2:30 PM to 5:30 PM. This indicates a gap of 3.5 hours between the two tests.
The official guidelines do not specify whether candidates are allowed to leave the exam center during this interval. Therefore, it's advisable to:
Check the Admit Card : Specific instructions regarding breaks may be mentioned.
Contact the Exam Center : Reach out directly to confirm their policy on leaving during the interval.
By taking these steps, you can ensure compliance with the exam center's policies and plan your day effectively.
