Answer:

Correct Answer: B

Solution:

  • 20% of 225 + 75 = ? % of 150

$ \Rightarrow $ $ \frac{20}{100}\times 225+75=\frac{?}{100}\times 150 $

$ \Rightarrow $ $ 45+75=\frac{?\times 150}{100} $

$ \Rightarrow $ $ ?\times \frac{3}{2}=120 $
$ \Rightarrow $ $ ?=\frac{2\times 120}{3}=2\times 40 $

$ \Rightarrow $ $ ?=80 $
