Answer 1

Step-by-step explanation:

Given :-

Amans age is three times his sons age. Ten years ago he was five times his sons age .

To find :-

find their age ?

Solution :-

Let the present age of Aman's son= X years

Then, Aman's present age = 3X years

Age of Aman ten years ago = (3X-10) years

Age of his son ten years ago = (X-10) years

Given that

Ten years ago he was five times his sons age

=>3X-10 = 5(X-10)

=>3X-10 = 5X-50

=>-10 + 50 = 5X - 3X

=>40 = 2X

=>2X = 40

=>X = 40/2

=>X =20

Age of his son= 20 years

Age of Aman= 3(20)=60 years

Answer :-

Present age of Aman = 60 years

Present age of his Son = 20 years

Check :-

Present age of his Son = 20 years

Present age of Aman = 3(20) = 60 years

Ten years ago their ages 10 and 50 years

Aman's age =5(10)=5 times his son's age
