Question

75% of 64 is 120% of:
A
38

Answer 1

48

Explanation:

We must first find what is 75% of 64 (x), in order to find what this number is 120% of (y).

To find percentages, we can use the formula
`(is)/(of)=(p percent)/(100)`, and we cross multiply and divide to find either the is value, of value, or the percent.

Thus, we have
`(x)/(64)=(75)/(100)\\ \\ 100x=(64*75)\\\\((100x=(64*75)))/(100) \\\\x=48`

Now we want to find what 48 is 120% of:

`(48)/(y)=(120)/(100) \\\\ 120y=(48*100)\\\\`

`((120y=(48*100))/(120) \\\\y=40`
