Therefore it's whole quantity (100%) would be
25(4)%->9(4)
It's whole quantity (100%) would be 36 units

Answer 2

Answer:

Required whole number is 36.

Step-by-step explanation:

Given, the whole quantity if 25% of it is 9.

Let the quantity be x.

So according to question,

$25\% \: of \: x = 9$

We Know, a% of b $= \frac{a}{100} \times b$

By som examples,we can understand this concept.

Example -1:

$5\% \: of \: 50 \\ = \frac{5}{100} \times 50 \\ = \frac{5}{2} \\ = 2.5$

Example -2:

$10\% \: of \: 500 \\ = \frac{10}{100} \times 500 \\ = 10 \times 5 \\ = 50$

Example -3:

$50\% \: of \: 750 \\ = \frac{50}{100} \times 750 \\ = 5 \times 75 \\ = 375$

Example -4:

$50\% \: of \: 1000 \\ = \frac{50}{100} \times 1000 \\ = 50 \times 10 \\ = 500$

So,

$25\% \: of \: x = 9 \\ \frac{25}{100} \times x = 9 \\ \frac{25x}{100} = 9 \\ 25x = 100 \times 9 \\ x = \frac{100 \times 9}{25} \\ x = 4 \times 9\\ x = 36$

Hence, value of x is 36.

So, required whole number is 36.
