Question

80% of a number is 96.

What is 25% of that same number?

A.
20

B.
30

C.
40

D.
120

Answer 1

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

Answer 2

`(80)/(100)*x=96` ⇒
`(80/20)/(100/20) *x=96`


`(4)/(5)*x=96` ⇒
`x= (96*5)/(4)=24*5`


`\boxed {x=120}`


`(25)/(100)*x= (25/25)/(100/25)*120 = (120)/(4) = \boxed {30}`

The answer is B.
