$▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

The required number is :

• $1$

$\large \boxed{ \mathfrak{Explanation}}$

Let the number be represented as " x "

from the given statement we can infer that :

• $7(x + 3) = 28$

So, let's find the value of " x " from the given equation ~

• $x + 3 = 28 \div 7$

• $x + 3 = 4$

• $x = 4 - 3$

• $x = 1$

Answer 2

Answer:

Let the required original number be " x "

According to the given problem,

$7(x + 3) = 28 \\ (x + 3) = \frac{28}{7} \\ (x + 3) = 4 \\ x =(4 - 3) \\ \boxed{x = 1}$

• Hence, the original number is 1.
• 1 is the right answer.
