Answer 1

Step-by-step explanation:

Answer :-

The present age of father and son is

Explanation :-

Given :

Present age of father = Six times the present age of his son.

After 4 years, the age of father will be four times the age of son.

To find :

Present age of father and son

Solution :

Let the present age of son be x

and the present age of father be 6x

After four years,

Age of son = (x + 4) years

Age of father = (6x + 4) years

According to question,

= > 6x + 4 = 4(x + 4)=>6x+4=4(x+4)

= > 6x + 4 = 4x + 16=>6x+4=4x+16

= > 6x - 4x = 16 - 4=>6x−4x=16−4

= > 2x = 12=>2x=12

= > x = \dfrac{12}{2}=>x=

2

12

= > x = 6=>x=6

Hence, the value of x is 6.

Now,

The age of son (x)= 6 years

The age of father (6x) => (6 × 6) = 36 years
