The correct answer is option (E):
3:4
The question asks for the ratio of low quality dye used for R type shirts to that used for S type shirts. To answer this, we need to extract the relevant information from the provided image, which appears to be a bar chart.
Looking at the bar chart, we can see that there are two types of shirts, R and S, and two types of dyes, high quality and low quality. We are interested in the low quality dye.
First, let's find the amount of low quality dye used for R type shirts. Locate the bar representing R type shirts and the segment of that bar representing low quality dye. Reading the value from the y-axis, we find that 3 units of low quality dye are used for R type shirts.
Next, let's find the amount of low quality dye used for S type shirts. Locate the bar representing S type shirts and the segment of that bar representing low quality dye. Reading the value from the y-axis, we find that 4 units of low quality dye are used for S type shirts.
The question asks for the ratio of low quality dye used for R type shirts to that used for S type shirts. This means we need to express the relationship between these two quantities as a ratio: (Low quality dye for R) : (Low quality dye for S).
Substituting the values we found, the ratio is 3 : 4.
Now, let's compare this ratio to the given options:
Option 1: 2:3
Option 2: 3:2
Option 3: 1:1
Option 4: 2:2, which simplifies to 1:1
Option 5: 3:4
Our calculated ratio of 3:4 matches Option 5. Therefore, the correct answer is 3:4.
