Question

Mykel is twice as old as James. Four years ago, he was thrice as old as James. How
old is Mykel now?​

Answer 1

Answer :-

Mykel is 16 years old now.

Step-by-step explanation:

Given that,

• Mykel is twice as old as James
• Mykel was thrice as old as James, four years ago.

Assumption:

Let us assume James's age as (x) years, and Mykel's age as (2x) years.

According the question,

• 2x = x

Also given, Four years ago.

• Age of James = (2x - 4) years
• Age of Mykel = 3(x - 4) years.

Therefore,

• 3(x - 4) = (2x - 4)

⇒ 3(x - 4) = (2x - 4)

⇒ 3x - 12 = 2x - 4

⇒ 3x - 2x = - 4 + 12

⇒ x = - 4 + 12

⇒ x = 8

The value of x is 8.

Now, The age of Mykel is :-

We assumed the age of Mykel as (2x) years, Therefore,

⇒ 2x

⇒ 2*8

⇒ 16 years.

Answer 2

Given :

• Mykel is twice as old as James.
• Four years ago, he was thrice as old as James.

To Find :

• Present age of Mykel

Solution :

Let,

• Present age of James = b
• Present age of Mykel = 2b

Four years ago,

• Age of James = b - 4
• Age of Mykel = 2b - 4

According to the Question :

⠀⟶⠀Age of Mykel = 3 × Age of James

⠀⟶⠀2b - 4 = 3(b - 4)

⠀⟶⠀2b - 4 = 3b - 12

⠀⟶⠀12 - 4 = 3b - 2b

⠀⟶⠀8 = b

Therefore :

• Present age of Mykel = 2b
• Present age of Mykel = 2 × 8
• Present age of Mykel = 16 years

So, Present age of Mykel is 16 years.
