is​

Answer 1

${\tt{\green{\underline{\underline{\huge{Answer}}}}}}$

$a \% \: of \: b = 48 \\ \\ \frac{a}{100} \times b = 48 \\ \\ \frac{ab}{100} = 48 \\ \\ ab = 48 \times 100 \\ \\ ab = 4800 \: \: \: \: \: \: \: ...(1)$

$b\% \: of \: a \: \\ \\ = \frac{b}{100} \times a \\ \\ = \frac{ab}{100} \\ \\ by \: eq(1) \\ \\ = \frac{4800}{100} \\ \\ = 48$

$\boxed {\sf \underline{answer = 48}}$

Answer 2

Answer:

48

Step-by-step explanation:

Let's take an example:

a = 30

b = 50

30% of 50 = 15

so if we reverse it..

50% of 30 = 15

As you can see, they are the same!

You can try this method with other numbers, and no matter what it will be the same. So your answer is 48.
