Answers
here is ur answer see the attachment
present age of father is 32 years
present age of son is 7 years
Let us assume that the present age of man be x years and the present age of his son be y years.
“Two years ago a man was 6 times as old as his son.”
Two years ago, the age of man = (x - 2) years
Two years ago, the age of son = (y - 2) years
According to question,
⇒ (x - 2) = 6(y - 2)
⇒ x - 2 = 6y - 12
⇒ x - 6y = -12 + 2
⇒ x - 6y = - 10
⇒ x = 6y - 10
Also, “After 18 years he will be twice as old as his son.”
After 18 years, the age of man = (x + 18) years
And the age of son = (y + 18) years
According to question,
⇒ (x + 18) = 2(y + 18)
⇒ x + 18 = 2y + 36
Substitute value of x from above
⇒ 6y - 10 + 18 = 2y + 36
⇒ 6y + 8 = 2y + 36
⇒ 6y - 2y = 36 - 8
⇒ 4y = 28
⇒ y = 7
Substitute value of y in x
⇒ x = 6(7) - 10
⇒ x = 42 - 10
⇒ x = 32
Therefore,
The present age of a man is 32 years and his son is 7 years.
