Given:-
To Find:-
Now,
Let' the Son's Present age be "x"
→ Aman's Present age = 3x
Atq. before 10 years
→ Aman's age = 3x - 10
→ Aman's Son's age = 5(x - 10)
So,
→ 3x - 10 = 5( x - 10)
→ 3x - 10 = 5x - 50
→ 3x - 5x = -50 + 10
→ -2x = -40
→ 2x = 40
→ x = 40/2
→ x = 20.
Therefore,
→ Aman Son's Present age = x → 20yrs
→ Aman's Present age = 3x → 3 × 20 → 60yrs.
Hence, Their Present ages are 20yrs and 60yrs Respectively.
Verified answer
Step-by-step explanation:
Let the age of his son's is. x.
So, Aman's present age is 3x.
Five years ago his son's age was (x-5).
Five years ago Aman's age was {5(x-5)}.
And also Aman's age of five years ago was (3x-5).
So,
(3x-5)={5(x-5)}
or,3x-5=5x-25
or, 5x-3x=25-5
or, 2x. =20
x=10
3x=30.
So, Aman's present age is 30 years& and his son's age is 10 years...
