Answers
Answer:
The age of sagar when tiru was born = 10 years
Step-by-step explanation:
It is given that,
Five years ago sagar was twice as old as tiru.
Ten years later sagar age will be ten year more than tiru age
Let x be the age of tiru five years ago.
Then the age of sager 5 years ago = 2x
Present age of tiru = x + 5
Present age of sagar = 2x + 5
After 10 years,
age of tiru = (x + 5 )+ 10 = x + 15
age of sagar = (2x + 5)+10 = 2x + 15
To find x
Ten years later sagar age will be ten year more than tiru age
we can write,
(x + 15) + 10 = 2x + 15
x + 25 = 2x + 15
x = 10
To find present age of tiru and sagar
Present age of tiru = x + 5 = 10 + 5 = 15
Present age of sagar = 2x + 5 = 2*10 + 5 = 25
To find the age of sagar when tiru was born
Present age of tiru = 15
Present age of sagar = 25
The age of sagar when tiru was born = Present age of sagar - present age of tiru = 25 - 15 = 10 years
Therefore the age of sagar when tiru was born = 10 years
