Question:medium

The following graph shows sales data of two products X and Y from 2015 to 2020 in Kgs. Study the graph of sales data carefully and answer the questions given below:
What is the percentage sales from product X in 2015 to the sales from product Y in 2020?

Show Hint

Divide sales of X in 2015 by sales of Y in 2020, then multiply by 100.
  • 25.72
  • 41.63
  • 46.26
  • 72.00
Show Solution

The Correct Option is A

Solution and Explanation

Step 1: Use a unitary method instead of direct division. Sales of Y in 2020 is 90300 kg, so 1 percent of it is $90300/100 = 903$ kg.
Step 2: Divide the sales of X in 2015 by this unit value: $23230/903 \approx 25.72$.
Step 3: So the sales of X in 2015 form about 25.72 percent of the sales of Y in 2020.
\[\boxed{25.72}\]
