Answer 1

Answer :

• Present age of son is 7.5 years
• Present age of father is 52.5 years

Given :-

• A fether is 45 years elder than his son.
• In 15 years, the father will be three times as old as his son.

To Find :-

• Their present age ?

Solution :-

• Let present age of son be y years.
• As it is stated question that a father is 45 years elder than his son. So, present age of father will be (y + 45) years.

★ Their ages after 15 years :

• Age of son = (y + 15) years
• Age of father = y + 45 + 15 = (y + 60) years.

★ According to the Question :

• In 15 years, the father will be three times as old as his son.

Therefore,

➻ Age of father = 3(Age of son)

➻ y + 60 = 3(y + 15)

➻ y + 60 = 3y + 45

➻ y - 3y = 45 - 60

➻ -2y = -15

➻ 2y = 15

➻ y = 15/2

➻ y = 7.5 years

• Hence, present age of son 7.5 years.

Now we know that,

➻ Present age of father = (y + 45) years

• Putting y = 7.5 we get,

➻ Present age of father = (7.5 + 45) years

➻ Present age of father = 52.5 years

• Hence, present age of father is 52.5 years.

Verification :-

• We know that according to the question, in 15 years, the father will be three times as old as his s,,on.

Therefore,

➻ Age of father = 3(Age of son)

➻ y + 60 = 3(y + 15)

• Putting y = 7.5 we get,

➻ 7.5 + 60 = 3(7.5 + 15)

➻ 67.5 = 3(22.5)

➻ 67.5 = 3 × 22.5

➻ 67.5 = 67.5

➻ LHS = RHS

• Hence, verified.
