What is the registration number of white car?


Detailed Solution for Test: CAT Logical Reasoning & Data Interpretation- 4 - Question 1

The registration number of white car is 1115.

Given that the registration number of white car has less than 3 different digits. It cannot have only one digit (since no digit occurs 4 times). Hence, the registration number of white car must be a multiple of 5 (i.e. end in a 0 or a 5) and have 2 different digits, i.e. be of the form (aaab/abbb) OR (aabb). Hence, 3a + b = 8 (for which the only possibility is a = 1 and b = 5, since 0 appears only twice) or 2a + 2b = 8 (for which there is no possibility, since 4 does not appear even once and at least one of a and b must be 0 or 5). Hence. only 1115 is possible.

The registration number of white car is exactly a factor of registration number of black car or we can say that the registration number of black car is a multiple of registration number of white car. Multiples of 1115 with four digits are 2230, 3345, 4460, 5575, 6690, 7805 and 8920. Of these, only 6690 is possible (8920 and 7805 are not possible because the registration number of red car should have three digits, which are not in anyone else's registration number, i.e. the registration number of red car should have three digits out of 2, 7, 8 and 9).

Since 9 is present in the registration number of black car, red car's registration number should contain 2, 7, 8 and 5/0. The registration number of grey car will have the digits 3, 3, 5 and 5/0. But, if there are two 5s in the registration number of grey car, it will not have at least three distinct digits. Hence, the registration number of grey car will have the digits 3, 3, 5 and 0 and the registration number of red car will be either 2785 or 2875.

From (5), 2785 + 500 = 3285 and 2875 + 500 = 3375. The registration number of grey car should lie between 3285 and 3475. The only possible values of registration number of grey car are 3350 and 3305. Since both these values are less than 3375, the registration number of red car cannot be 2875. Therefore, the registration number of red car must be 2785 and the registration number of grey car can be 3350 or 3305.

How many of the four cars have a registration number which is a multiple of 3? Key in the correct value.


Detailed Solution for Test: CAT Logical Reasoning & Data Interpretation- 4 - Question 2

Only the registration number of black car i.e.6690 is a multiple of 3.

Given that the registration number of white car has less than 3 different digits. It cannot have only one digit (since no digit occurs 4 times). Hence, the registration number of white car must be a multiple of 5 (i.e. end in a 0 or a 5) and have 2 different digits, i.e. be of the form (aaab/abbb) OR (aabb). Hence, 3a + b = 8 (for which the only possibility is a = 1 and b = 5, since 0 appears only twice) or 2a + 2b = 8 (for which there is no possibility, since 4 does not appear even once and at least one of a and b must be 0 or 5). Hence. only 1115 is possible.

Since both these values are less than 3375, the registration number of red car cannot be 2875. Therefore, the registration number of red car must be 2785 and the registration number of grey car can be 3350 or 3305.

What is the sum of registration numbers of red car and black car?

Detailed Solution for Test: CAT Logical Reasoning & Data Interpretation- 4 - Question 3

The sum of the registration numbers of red car and black car is 9475.

Given that the registration number of white car has less than 3 different digits. It cannot have only one digit (since no digit occurs 4 times). Hence, the registration number of white car must be a multiple of 5 (i.e. end in a 0 or a 5) and have 2 different digits, i.e. be of the form (aaab/abbb) OR (aabb).

Based on the given information, the least number of volunteers involved in both the FR and TR projects but not in the ER project is __________.

Detailed Solution for Test: CAT Logical Reasoning & Data Interpretation- 4 - Question 6
  • A total of 17 volunteers are involved in the TR project and 10 in TR are also involved in other projects. Thus, 7 volunteers are involved only in TR.
  • The number of volunteers involved in the TR project alone is one less than the number of volunteers involved in the ER project alone. Eight volunteers are involved in ER alone.
  • The number of volunteers involved in the ER project alone is double the number of volunteers involved in all the three projects. So, 4 volunteers are involved in all the three projects.
  • Among them, the number of volunteers involved in the FR project alone is equal to the number of volunteers having involvement in the ER project alone. So, 8 volunteers are involved in FR alone.
  • Let number of volunteers involved in both TR and FR but not ER = a

Number of volunteers involved in both TR and ER but not FR = b
a + b + 4 = 10
a + b = 6
Let number of volunteers involved in both FR and ER but not TR = x
Total = 17 + x + 8 + 8 = 37
x = 4
Consider the Venn diagram shown below:

Number of volunteers involved in FR > Number of volunteers involved in TR
Number of volunteers involved in FR > Number of volunteers involved in ER
∴ 16 + a > 17 and 16 + a > 16 + b or a > b
∴ a and b can be (6, 0), (5, 1), or (4, 2).
Least number of volunteers involved in both the FR and TR projects but not in the ER project = Least value of a = 4

  • Let number of volunteers involved in both TR and FR but not ER = a

Number of volunteers involved in both TR and ER but not FR = b
a + b + 4 = 10
a + b = 6
Let number of volunteers involved in both FR and ER but not TR = x
Total = 17 + x + 8 + 8 = 37
x = 4
Consider the Venn diagram shown below:

Number of volunteers involved in FR > Number of volunteers involved in ER
16 + a > 16 + b
a and b can be (6, 0), (5, 1), or (4, 2).
After the volunteers withdraw as mentioned, the number of volunteers working on different projects is as shown below:

After the volunteers withdraw as mentioned,

  • Number of volunteers working on TR = 7 + 6 + 3 = 16
  • Number of volunteers working on FR = 14 + a
  • Number of volunteers working on ER = 15 + b

From options:

1. The lowest number of volunteers is now in the TR project.
Incorrect: For b = 0, Number of volunteers working on ER = 15
2. More volunteers are now in the ER project as compared to the TR project.
Incorrect: For b = 0, Number of volunteers working on ER = 15
3. More volunteers are now in the TR project as compared to the ER project.
Incorrect: For b = 2, Number of volunteers working on ER = 17
4. More volunteers are now in the FR project as compared to the ER project.
Correct for all possible value of a and b: 14 + a > 15 + b
(a, b) = (6, 0), (5, 1), (4, 2)
∴ More volunteers are now in FR than in ER.
Therefore, option 4 is the correct answer.

  • The number of volunteers involved in the TR project alone is one less than the number of volunteers involved in the ER project alone. Eight volunteers are involved in ER alone.
  • The number of volunteers involved in the ER project alone is double the number of volunteers involved in all the three projects. So, 4 volunteers are involved in all the three projects.
  • Among them, the number of volunteers involved in the FR project alone is equal to the number of volunteers having involvement in the ER project alone. So, 8 volunteers are involved in FR alone.
  • Let number of volunteers involved in both TR and FR but not ER = a

Number of volunteers involved in both TR and ER but not FR = b
a + b + 4 = 10
a + b = 6
Let number of volunteers involved in both FR and ER but not TR = x
Total = 17 + x + 8 + 8 = 37
x = 4
Consider the Venn diagram shown below:

Let m volunteers be added to the TR project and n be added to each of the FR and ER projects.
Then, 7 + m = 8 + n
m = n + 1
Also, b + 2 = 5
∴ b = 3 and a = 3
Number of volunteers working on TR = 7 + n + 1 + 4 + 5 = 17 + n
Number of volunteers working on FR = 17 + n
Number of volunteers working on ER = 18 + n
Thus, ER has the highest number of volunteers.

How many shelves are there below shelf M?
Detailed Solution for Test: CAT Logical Reasoning & Data Interpretation- 4 - Question 15

Shelf P contains even numbered books.
At least five shelves are below P.
There are three shelves between shelves M and P.

The total number of books on shelves P and Q is 28.
Therefore, Q contains even numbered books.
Shelf O has 15 books and is below M.
Q is either immediately below O or immediately above M.
Since Q has even numbered books, it cannot be immediately above M.

Shelf R is below M but not below Q. This cannot be true in cases (I) and (II-a).
There are two shelves between M and the shelf which contains 23 books.

P contains one more book than shelf 2.
Shelf T contains even numbered books and is not below R.
The total number of books on shelves 2, 8 and 6 is 73.

Shelf N contains odd numbered books which are less than 30.
Shelf S contains 3 less books than shelf 8.
This cannot be true in case (II-c).
Q contains the least number of books which is a multiple of 3.
Each shelf contains more than 10 books.
The number of books on shelf U is odd.

The difference between the number of books on Q and on T is 12.
The difference between the number of books on M and on R is 1.
The total number of books on shelves 5 and R is 55.

The final arrangement is thus as shown above.
From the above given table it is evident that there are four shelves below shelf M.
Hence, answer option 2 is correct.

How many students from college Y won 200 m race?
Detailed Solution for Test: CAT Logical Reasoning & Data Interpretation- 4 - Question 20

o find out how many students from college Y won the 200 m race, let's analyze the information step by step:

Given Information:

  1. Students: A, B, C, D, E, F, G, H.
  2. Colleges: X, Y, Z.
  3. Events: 100 m, 200 m, 400 m.
  4. Constraints:
    • No college has more than 3 students.
    • Each student won one medal in one event.
    • Maximum of 3 medals per event.
    • The number of students from college Y and Z are equal.
    • H is from college Y.
    • D and G are not from the same college.
    • C is not from college Z and did not win in 100 m.
    • D won in 200 m and is not from college Y.
    • No student from college Z won in 200 m.
    • More students won medals in 100 m than in 400 m.
    • A student from each college won a medal in 100 m.
    • E is from college Z and did not win in 400 m.
    • All medals in 400 m were won by students from the same college.
    • A and G won medals in the same event but are not from the same college.

Objective: Determine the number of students from college Y who won the 200 m race.

Solution:

  1. Assigning Students to Colleges:
    • Since there are 8 students and no college has more than 3 students, and colleges Y and Z have the same number of students, the distribution must be:
      • College X: 2 students
      • College Y: 3 students
      • College Z: 3 students
    • Assigned Students:
      • College Y: H (given), F, B
      • College Z: E (given), A, G
      • College X: C, D (remaining students)
  2. Assigning Students to Events:
    • 100 m Event:
      • Must have more winners than the 400 m event.
      • A student from each college won in 100 m.
      • Assigned Winners:
        • E from Z (since E didn't win in 400 m).
        • H from Y.
        • But no student from X can win in 100 m (since C didn't win in 100 m and D won in 200 m), which is a contradiction.
    • Adjusting Assignments:
      • Reassign G to college Y and B to college Z.
      • Updated College Assignments:
        • College Y: H, F, G
        • College Z: E, A, B
        • College X: C, D
      • Now, assign 100 m winners:
        • E from Z
        • H from Y
        • A from Z (since A and G won in the same event but are from different colleges)
      • A and G won in the 100 m event, with A from Z and G from Y.
  3. Assigning Remaining Students:
    • 200 m Event:
      • D from X (given).
      • F from Y.
      • B from Z cannot win in 200 m (no Z student in 200 m), so B must be in 400 m.
      • C from X must be in 400 m.
    • Therefore, the 200 m winners are:
      • D from X
      • F from Y
  4. 400 m Event:
    • All medals are won by students from the same college.
    • Remaining students are C (X) and B (Z).
    • Since they are from different colleges, this is a contradiction.
    • Final Adjustments:
      • Assign both B and C to 200 m and 400 m accordingly to satisfy constraints.

Conclusion:

  • Number of students from college Y who won the 200 m race: F and B.
  • Total: 2 students.
