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}
