Question

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel. How old is Kevin now?

Answer 1

Answer:

6

Step-by-step explanation:

Let Daniel's age be x

Kevin's age will be x+3

Two years ago

Daniel will be x-2

Kevin will be (x+3) - 2

(x+3) - 2 = 4(x-2)

x+1 = 4x -8

-3x = -9

x = 3

Daniel's age is 3 years

Kevin's age is 6 years

Answer 2

Answer:

Present age of Kevin is 6 years

Step-by-step explanation:

Given:

• Kevin is 3 years older than Daniel

• 2 years ago Kevin was 4 times as old as Daniel

To find:

• Present age of Kevin

Solution :

Let,

Present age of Daniel = x

Present age of Kevin = x + 3

Two years ago,

The age of Daniel = x - 2

The age of Kevin = x + 3 - 2 =

( x + 3 - 2) = x + 1

Also,

Kevin was 4 times as old as Daniel

So,

⇒ 4 (x - 2) = x + 1

⇒ 4x - 8 = x + 1

⇒ 4x - x = 1 + 8

⇒ 3x = 9

⇒ x = 9 / 3

⇒ x = 3

★ Present age of Daniel = 3 years

Present age of Kevin = x + 3

⇒ 3 + 3

⇒ 6

★ Present age of Kevin = 6 years

Therefore,

Present age of Kevin is 6 years.
