Question

The age of a man is three times the age of his son. After 10 years, the age of the man will be double that of the son. Assuming the age of the son to be x, obtain a relation and find their present ages.​

Answer 1

Step-by-step explanation:

let the son's age be x

the man's age = 3x

after 10 years,

sons age = x+ 10

man's age = 3x+ 10

so, according to the question,

3x+10 = 2(x+10)

= 3x + 10 = 2x + 20

=> x = 10

so the present age of son is 10 and age of the man is 30
