Question

A son is 30years younger than his father . After 4years father will be three times as old as his son find their present age​

Answer 1

Present age of Son = 11 years

Present age of Father = 41 years

Step-by-step explanation:

Solution :

Let,

• Present age of Son = x
• Present age of Father = x + 30

After 4 years,

• Age of Son = x + 4
• Age of Father = x + 30 + 4 = x + 34

Also,

Father will be three times as old as his son

★ According to the Question :

⇒ 3 (x + 4) = x + 34

⇒ 3x + 12 = x + 34

⇒ 3x - x = 34 - 12

⇒ 2x = 22

⇒ x = 22/2

⇒ x = 11

Present age of Son = 11 years

• Present age of Father = x + 30

⇒ x + 30

⇒ 11 + 30

⇒ 41

Present age of Father = 41 years

Therefore,

Present age of Son = 11 years

Present age of Father = 41 years
