DILR Preparation: Important Topics for DILR Expected in CAT 2024

Given below are the important CAT quantitative aptitude topics based on the previous year’s question papers and current exam trends.

Examples of CAT DILR: Graphs

1. Study the scatter graph given below which contains the sales of a firm during the first 6 months of 2023 and answer the questions that follow. Sales are measured in dollars

In which month was the greatest improvement in sales seen?

1. January

2. March

3. April

4. May

Solution:

The difference in sales is given by:

February to January: 15,000 - 10,000 = 5,000

March to February: 40,000 - 15,000 = 25,000

April to March: 25,000 - 40,000 = -15,000 (This is a drop in sales)

May to April: 35,000 - 25,000 = 10,000

June to May: 30,000 - 35,000 = -5,000 (This is a drop in sales)

The greatest improvement in sales is observed in March, where sales increased by 25,000 compared to the previous month, February. So, the greatest improvement was seen in March.

2. In which month was the greatest dip seen?

1. February

2. May

3. April

4. June

Solution:

The difference in sales is given by:

February to January: 15,000 - 10,000 = 5,000

March to February: 40,000 - 15,000 = 25,000

April to March: 25,000 - 40,000 = -15,000 (This is a drop in sales)

May to April: 35,000 - 25,000 = 10,000

June to May: 30,000 - 35,000 = -5,000 (This is a drop in sales)

Therefore, the greatest dip is observed in April, where sales decreased by 15,000 compared to the previous month, March. So, the greatest dip was seen in April.

3. What is the ratio of total sales in the first three months to total sales in the last three months?

1. 13:18

2. 18:13

3. 1:3

4. 3:1

Solution:

Total Sales in the First Three Months:

January: $10,000

February: $15,000

March: $40,000

Total Sales in the First Three Months = 10,000 + 15,000 + 40,000 = 65,000

Total Sales in the Last Three Months:

April: $25,000

May: $35,000

June: $30,000

Total Sales in the Last Three Months = 25,000 + 35,000 + 30,000 = 90,000

Ratio = Total Sales in the First Three Months / Total Sales in the Last Three Months

Ratio = 65,000 / 90,000

So, the ratio of total sales in the first three months to total sales in the last three months is 13:18.

4. Find the average sales in dollars

1. $15,000

2. $25,000

3. $20,000

4. $25,833.33

Solution:

Given,
January: 10,000
February: 15,000
March: 40,000
April: 25,000
May: 35,000
June: $30,000

Total Sales = 10,000 + 15,000 + 40,000 + 25,000 + 35,000 + 30,000 = 155,000

Number of Months = 6

Now, calculate the average sales:

Average Sales = Total Sales / Number of Months

Average Sales = 155,000 / 6

Average Sales = 25,833.33 (rounded to two decimal places)

So, the average sales in dollars is approximately 25,833.33.

5. Find the difference between the month that had the highest sales and the month that had the least.

1. $25,000

2. $40,000

3. $5,000

4. $30,000

Solution:

Given the sales in dollars:

March had the highest sales with $40,000.

January had the least sales with $10,000.

To find the difference:

Difference = Sales in March - Sales in January

Difference = 40,000 - 10,000

Difference = $30,000

So, the difference between the month with the highest sales (March) and the month with the least sales (January) is $30,000.
