Answer 2

Answer:

The three digit number is 624

Step-by-step explanation:

Let,

Tens digit = x

Ones digit = 2x

Hundreds digit = 3x

According to question :

The average of the three digits is 4

So,

As we know,

★ $Average \: = \frac{Sum \: of \: Observation}{No. \: of \: Observation}$

⇒ $\: \frac{x \: + \: 2x \: + 3x }{3} \: = \: 4$

⇒$\: \frac{6x}{3} = \: 4$

⇒ 6x = 4 × 3

⇒ 6x = 12

⇒ x = 12 / 6

⇒ x = 2

____________________________

★ Value of 2x:

⇒ 2 (2)

⇒ 2 × 2

⇒ 4

___________________________

★ Value of 3x

⇒ 3 (2)

⇒ 3 × 2

⇒ 6

Therefore,

The three digit number is 624
