Answer: The answer is (a) The first paint mixture is yellower than the second mixture.
Step-by-step explanation: Given that there are two orange mixtures as follows -
In the first mixture, there are 3 parts red and 5 parts yellow. So, the proportions of red and yellow are
![r_1=\dfrac{3}{3+5}=\dfrac{3}{8}=0.375](https://tex.z-dn.net/?f=r_1%3D%5Cdfrac%7B3%7D%7B3%2B5%7D%3D%5Cdfrac%7B3%7D%7B8%7D%3D0.375)
and
![y_1=\dfrac{5}{3+5}=\dfrac{5}{8}=0.625.](https://tex.z-dn.net/?f=y_1%3D%5Cdfrac%7B5%7D%7B3%2B5%7D%3D%5Cdfrac%7B5%7D%7B8%7D%3D0.625.)
In the second mixture, there are 4 parts red and 6 parts yellow. So, the proportions are
![r_2=\dfrac{4}{4+6}=\dfrac{4}{10}=0.4](https://tex.z-dn.net/?f=r_2%3D%5Cdfrac%7B4%7D%7B4%2B6%7D%3D%5Cdfrac%7B4%7D%7B10%7D%3D0.4)
and
W
Hence,
i.e., the proportion of yellow in first mixture is more than in the second mixture.
Thus, the first mixture is yellower than the second mixture.
