Answer: B. 33%
Step-by-step explanation:
We use Mathematical Formula : [tex]\dfrac{\text{Difference between the Weight of 0.20 and Weight of 0.15 }}{\text{Weight of 0.15}}\times100[/tex]
Since , Difference between the Weight of 0.20 and Weight of 0.15 = 0.20-0.15=0.05
Then, substitute the value in formula , we get
[tex]=\dfrac{0.05}{0.15}\times100\\\\=\dfrac{5}{15}\times100\\\\ \dfrac{100}{3}\%\approx33\%[/tex]
Hence, the weight of 0.20 is 33% more important than a weight of 0.15.
