Download NowData Interpretation (DI) challenges often involve extracting and analyzing information from various data formats. Tables, being a straightforward yet versatile format, are a favorite in exams. Below is a sample DI problem based on a table, followed by a step-by-step solution that illustrates how to approach these questions effectively.
Example Problem: Sales Data Analysis
You are given the following table showing the sales figures (in units) for three different products (Product A, Product B, Product C) over four quarters of a year.
Quarter | Product A | Product B | Product C |
---|---|---|---|
Q1 | 150 | 200 | 250 |
Q2 | 200 | 240 | 300 |
Q3 | 250 | 300 | 350 |
Q4 | 300 | 360 | 400 |
Question:
Calculate the percentage increase in total sales from Q1 to Q4.
Step-by-Step Solution:
Step 1: Calculate Total Sales for Q1 and Q4
First, we need to find the total sales for both quarters.
-
Q1 Total Sales = Sales of Product A + Product B + Product C in Q1 = 150 (A) + 200 (B) + 250 (C) = 600 units
-
Q4 Total Sales = Sales of Product A + Product B + Product C in Q4 = 300 (A) + 360 (B) + 400 (C) = 1060 units
Step 2: Calculate the Increase in Sales
To find the increase, subtract the Q1 total from the Q4 total.
- Increase in Sales = Q4 Total Sales – Q1 Total Sales = 1060 units (Q4) – 600 units (Q1) = 460 units
Step 3: Calculate the Percentage Increase
The percentage increase is calculated by dividing the increase in sales by the total sales in Q1 and then multiplying by 100.
- Percentage Increase = (Increase in Sales / Q1 Total Sales) × 100 = (460 / 600) × 100 = 76.67%
Conclusion:
The total sales increased by 76.67% from Q1 to Q4. This significant increase highlights the overall positive sales performance across all products.
