The following line graph shows the production of two products A and B in a company over different years. In which year is the combined production of A and B the highest?

1. A

   2015

2. B

   2017

3. C

   2018

4. D

   2016

Explanation

• To solve this, you must find the sum of production for both products (A and B) for each year shown in the options.
• In 2015, the solid line (Product A) is at 35 units.
• In the same year, the dotted line (Product B) is at 25 units.
• The combined production for 2015 is the sum of these two values: 35 + 25 = 60 units.
• Comparing this total with the totals from other years (55 in 2016, 40 in 2017, and 57.5 in 2018) shows that 2015 had the highest combined production.

Why Other Options Were Wrong

• Option B: In 2017, the combined production was 25 (Product A) + 15 (Product B) = 40. This is the lowest among the given options.
• Option C: In 2018, the combined production was approximately 40 (Product A) + 17.5 (Product B) = 57.5. While production of A was highest this year, the combined total is less than that of 2015.
• Option D: In 2016, the combined production was 20 (Product A) + 35 (Product B) = 55. This is lower than the combined production in 2015.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Data interpretation from a line graph as background academic context rather than a clinical decision trigger.
• While this is a general aptitude question, the skill of interpreting graphs is crucial in nursing.
• Nurses frequently analyze charts and graphs to monitor patient vitals (like temperature, blood pressure, heart rate over time), track lab value trends, and interpret growth charts for pediatric patients.
• Accurate data interpretation is essential for making correct clinical decisions and identifying changes in a patient's condition.

How to Approach the Question

• First, understand the question: It asks for the year with the highest combined production of two products.
• Identify the components of the graph: The x-axis shows years, the y-axis shows production units, the solid line is Product A, and the dotted line is Product B.
• For each year listed in the options (2015, 2016, 2017, 2018), carefully read the value for Product A and Product B from the y-axis.
• Calculate the sum of the two values for each year.
• Create a simple table to keep your calculations organized.
• Compare the total (combined) production for each year and identify the largest sum. The year corresponding to this sum is the correct answer.
