The present age of father = 80

The present age of son= 20

Step-by-step explanation:

Let the age of father be 'F' and age of son be 'S'

According to question-:

Age of father is four times the age of his son.

F=4S[eq.1]

After 10 years Condition-:

Age of father will become three times the age of his son.

F+10=3(S+10)[eq.2]

10 come here because the condition is after 10 years.✓✓✓

Now, Substituting F=4S in eq.2

we get,

=> 4S+10=3S+30

=> [S=20]✓✓✓✓✓

Substituting S=20 in eq.1

we get,

F=4*20

F=80

Let son's age is = x

than father's age is =4x

AFTER 10 YEAR

father will be 3 times than him

According to question

4x+10= 3 (x+10)

4x+10=3x+30

4x- 3x=30-10

x=20

therefore son's present age is 20

and father's present age is 80

Let the present age be x

father age be 4x

Ten years hence father age be 3 times the age of his son

A/Q

$\implies$ 4x+10=3(x+10)

$\implies$ 4x+10=3x+30

$\implies$ 4x-3x=30-10

$\implies$ x=20

Son age =20years

Father age=4×20=80years.

Father is 80 years old and son is 20 years old.

Step-by-step explanation:

Given :

Present age of father = four times the age of his son

After 10 years = Father will become three times the age of his son

To find :

Present age of father

Solution :

$\textbf{\small{\underline{Let the present ages be - }}}$

Son as x Father as 4x

$\textbf{\small{\underline{After 10 years - }}}$

Son = (x + 10) Father = (4x + 10)

$\textbf{\small{\underline{According to the Question -}}}$

After 10 years = Father will become three times the age of his son

$\rm{\implies} \: (4x + 10) =3(x + 10) \\ \rm{\implies} \: 4x + 10 = 3x + 30 \\ \rm{\implies} \: 4x - 3x = 30 - 10 \\ \rm{\implies} \: x = 20$

Son's present age = 20 years

$\rule{300}{1.5}$

★ Value of 4x

$\rm{\implies} \: 4(20) \\ \rm{\implies} \: 80$

Father's age = 80 years old

$\therefore$ Father is 80 years old and son is 20 years old.

The correct answer was given: bhavya1650

father's age 80, son's age=20

Step-by-step explanation:

let the son age be x and father age 4x

after 10 years=4x+10

A/Q

(4x+10)=3(x+10)

(4x+10)=3x+30

4x-3x=30-10

x=20

Hence,the age of son is 20 years and the age of father is 20×4=80 years.

The correct answer was given: sandhu2840

present age of father = 80 years

present age of his son = 20 years

Step-by-step explanation:

let the present age of father = x

and present age of his son = y

A.T.Q

x = 4y (1)

(x + 10) = 3(y + 10)

x + 10 = 3y + 30

x - 3y = 30 - 10

x - 3y = 20 (2)

put x = 4y in eq 2

4y - 3y = 20

y = 20

put y in eq 1

x = 4y

x = 4 × 20

x = 80
