Answer:
Present age of son 1 year 2 months.
Step-by-step explanation:
Given :-
- A man's present age is 8 times more than his son.
- After 10 years, he will be twice the age of his son.
To find :-
- Present age of son.
Solution :-
Consider,
- Present age of son = x years
★ A man's present age is 8 times more than his son.
Then,
- Present age of the man = 8x years
After 10 years,
- Son's age = (x+10) years
- Man's age = (8x+10) years
★After 10 years, he will be twice the age of his son.
According to the question,
8x+10 = 2(x+10)
→ 8x + 10 = 2x + 20
→ 8x-2x = 20-10
→ 6x = 10
→ x = 5/3
→ x = 1 year 2 months
★ Present age of son = 1 year 2 months.
★ Present age of man = 8 × 5/3 = 40/3 = 13 years 1 month.
