　　Solution for DILR 2018 Slot 2 (Hypothetical Example)

Assuming a common DI-LR question type, here’s a structured approach to solve a sample question:

　　Question (Data Interpretation):

A survey tracks the sales (in thousands) of two products (X and Y) over four years. The table below shows the data:

Year
Product X
Product Y
Total Sales

2015
40
30
70

2016
50
35
85

2017
60
40
100

2018
45
50
95

　　Q1: In which year did the growth rate of Product Y sales exceed the growth rate of Product X sales?

Q2: What is the ratio of cumulative sales of Product X to Product Y from 2015 to 2018?

　　Step-by-Step Solution:

Calculate Year-over-Year Growth Rates:

Growth Rate Formula:

[
\text{Growth Rate} = \frac{\text{Current Year Sales} - \text{Previous Year Sales}}{\text{Previous Year Sales}} \times 100
]
Product X Growth Rates:
2016: (\frac{50-40}{40} \times 100 = 25%)
2017: (\frac{60-50}{50} \times 100 = 20%)
2018: (\frac{45-60}{60} \times 100 = -25%) (Decline)

Product Y Growth Rates:
2016: (\frac{35-30}{30} \times 100 = 16.67%)
2017: (\frac{40-35}{35} \times 100 \approx 14.29%)

2018: (\frac{50-40}{40} \times 100 = 25%)

Answer Q1:

Compare growth rates year-wise:

2016: X (25%) > Y (16.67%)
2017: X (20%) > Y (14.29%)
2018: X (-25%) < Y (25%)

Answer: 2018

Answer Q2:

Cumulative Sales of X: (40 + 50 + 60 + 45 = 195)
Cumulative Sales of Y: (30 + 35 + 40 + 50 = 155)
Ratio: (\frac{195}{155} = \frac{39}{31}) (Simplified)

Answer: (39:31)

　　Final Answers:

Q1. \boxed{2018}

Q2. \boxed{39:31}
