Age of father is 30 years more than that of his son, 5 years hence fathers age will be thrice of his sons age. Find their present ages

Answers

Answer:

Son age be 10

And, the father age be 40

Step-by-step explanation:

The computation of the present ages is shown below:

Let us assume the son age be x

And, the father age be x + 30

Now after five hence, their ages are

Son age = x + 5

And, the father age be = x + 30 + 5

Also the father age is thrice of his son age

So the equation would be

3(x + 5) = x + 35

3x + 15 = x + 35

2x = 20

x = 10

The son age is 10

And, the father age is = 10 + 30 = 40

The correct ans is Five,

Let the son’s present age be x years.

Then the father’s present age is (x+30) years.

Father’s age after 5 years =(x+40) years

Son’s age after 5 years = (x+5) years

(x+40) = 3[x + 5]

x + 40 = 3x + 15

2x = 10

∴ x = 5
