Step-by-step explanation:
80% of p = 20
=> 0.8p = 20, p = 20 / 0.8 = 25.
75% of b = 12
=> 0.75b = 12, b = 12 / 0.75 = 16.
Answer:
[tex]80\% \: of \: p = 20 \\ \frac{80}{100} p = 20 \\ \frac{4}{5} p = 20 \\ p = \frac{20 \times 5}{4} \\ \boxed{p = 25}[/tex]
25 is the right answer.
[tex]75\% \: of \: b = 12 \\ \frac{75}{100} b = 12 \\ \frac{3}{4} b = 12 \\ b = \frac{12 \times 4}{3} \\ \boxed{b = 16}[/tex]
