Question

the present age of father is thrice the age of his son's present age.The sum of their ages 5 years hence will be 82 years. Find their present age?​

Answer 1

Answer:

Age of son is 18

Age of father is 54

Step-by-step explanation:

Let the present age of son be x

Let the present age of father be 3x

Their age after 5 years:

Father: 3x + 5

Son: x + 5

Sum of their age after 5 years = 82

3x + 5 + x + 5 = 82

4x + 10. = 82

4x. = 82 - 10

x. = 72/4 = 18

Present age of son is x = 18

Present age of father is 3x = 3×18 = 54

Answer 2

Given :

⬤ Present Age of Father is thrice the age of his Son's Present age .

⬤ Sum of their ages 5 years hence will be 82 years .

To Find :

⬤ Present age of Father and Son .

Solution :

Let :

• Son age be x .
• Father age be 3x.

After 5 years :

• Son age = x + 5 .
• Father age = 3x + 5 .

Now :

$\sf{x+5+3x+5=82}$

x + 3x + 5 + 5 = 82

4x + 10 = 82

4x = 82 - 10

4x = 72

x = 72/4

x = 18

Therefore , The Value of x is 18 .

Hence ,

Age of Son = x

= 18

Age of Father = 3x

= 3(18)

= 54

Therefore , The Age of Son is 18 years and Age of Father is 54 years .
