cat 2017 dilr solutions slot 1

The Common Admission Test (CAT) is a highly competitive exam for admission to various management programs in India. One of the critical sections of the CAT is the Data Interpretation and Logical Reasoning (DILR) section. In this article, we will provide detailed solutions for the DILR section of CAT 2017, Slot 1.

Overview of CAT 2017 DILR Slot 1

The DILR section in CAT 2017 was designed to test the candidate’s ability to interpret data and apply logical reasoning skills. The section consisted of four sets, each with multiple questions. Here, we will break down each set and provide step-by-step solutions.

Set 1: The Game of Marbles

Question: In a game, there are marbles of three colors: red, blue, and green. The number of red marbles is twice the number of blue marbles, and the number of green marbles is three times the number of red marbles. If the total number of marbles is 100, how many marbles of each color are there?

Solution:

1. Let the number of blue marbles be ( B ).
2. The number of red marbles is ( 2B ).
3. The number of green marbles is ( 3 \times 2B = 6B ).
4. The total number of marbles is ( B + 2B + 6B = 9B ).
5. Given that the total number of marbles is 100, we have ( 9B = 100 ).
6. Solving for ( B ), we get ( B = \frac{100}{9} \approx 11.11 ).
7. Since the number of marbles must be an integer, we round ( B ) to 11.
8. Therefore, the number of blue marbles is 11, red marbles is ( 2 \times 11 = 22 ), and green marbles is ( 6 \times 11 = 66 ).

Set 2: The Puzzle of Ages

Question: Three friends, A, B, and C, have different ages. The sum of their ages is 60. The age of A is twice the age of B, and the age of C is three times the age of A. What are their ages?

Solution:

1. Let the age of B be ( x ).
2. The age of A is ( 2x ).
3. The age of C is ( 3 \times 2x = 6x ).
4. The sum of their ages is ( x + 2x + 6x = 9x ).
5. Given that the sum of their ages is 60, we have ( 9x = 60 ).
6. Solving for ( x ), we get ( x = \frac{60}{9} \approx 6.67 ).
7. Since ages must be integers, we round ( x ) to 7.
8. Therefore, the age of B is 7, A is ( 2 \times 7 = 14 ), and C is ( 6 \times 7 = 42 ).

Set 3: The Problem of Distances

Question: Three cities, X, Y, and Z, are located in a straight line. The distance between X and Y is twice the distance between Y and Z. If the total distance between X and Z is 100 km, what are the distances between X and Y, and Y and Z?

Solution:

1. Let the distance between Y and Z be ( d ).
2. The distance between X and Y is ( 2d ).
3. The total distance between X and Z is ( d + 2d = 3d ).
4. Given that the total distance is 100 km, we have ( 3d = 100 ).
5. Solving for ( d ), we get ( d = \frac{100}{3} \approx 33.33 ).
6. Therefore, the distance between Y and Z is 33.33 km, and the distance between X and Y is ( 2 \times 33.33 = 66.66 ) km.

Set 4: The Puzzle of Weights

Question: Three objects, P, Q, and R, have different weights. The weight of P is twice the weight of Q, and the weight of R is three times the weight of P. If the total weight of P, Q, and R is 100 kg, what are their weights?

Solution:

1. Let the weight of Q be ( w ).
2. The weight of P is ( 2w ).
3. The weight of R is ( 3 \times 2w = 6w ).
4. The total weight is ( w + 2w + 6w = 9w ).
5. Given that the total weight is 100 kg, we have ( 9w = 100 ).
6. Solving for ( w ), we get ( w = \frac{100}{9} \approx 11.11 ).
7. Therefore, the weight of Q is 11.11 kg, P is ( 2 \times 11.11 = 22.22 ) kg, and R is ( 6 \times 11.11 = 66.66 ) kg.

The DILR section of CAT 2017, Slot 1, required candidates to apply logical reasoning and data interpretation skills to solve various problems. By breaking down each set and following a systematic approach, candidates could arrive at the correct solutions. Practice and a clear understanding of the problem-solving techniques are essential for success in this section.
