Question

If half of half of a number is 20, then the number is?

Answer 1

the half of half of a number is 20 then the number is 80

Answer 2

Answer:

If half of half of a number is 20, then the number is 80.

Step-by-step explanation:

Let us assume that the number is x

According to the question, the resultant of a half of a specific number when again halved gives us the value 20. We can write the following statement in the form of a mathematical equation:

$\frac{x}{2} \times \frac{1}{2} = 20$

⇒ $\frac{x}{2} = 40$

⇒ $x = 80$

Thus, 80 when halved gives us 40, which if again halved gives us the value 20.
