\(\frac{80}{100}*x=96\) ⇒ \(\frac{80\div20}{100\div20} *x=96\)

\(\frac{4}{5}*x=96\) ⇒ \(x= \frac{96*5}{4}=24*5\)

\(\boxed {x=120}\)

\(\frac{25}{100}*x= \frac{25\div25}{100\div25}*120 = \frac{120}{4} = \boxed {30}\)

The answer is B.

let the number be x
80%*x=96
x=96/80%
x=120
then 25% of 120 is your answer to find this half 120 twice
half 120=60
half 60=30

Therefore 30 is the answer which is B
