Answer:
Step-by-step explanation:
Given :
To find :
their present ages
Solution :
Let the present age of Ram be x years.
His mother is thrice as old as Ram.
So, the present of his mother = 3x years
10 years ago,
Ram's age = (x - 10) years
His mother's age = (3x - 10) years
According to the question,
3x - 10 = 7(x - 10)
3x - 10 = 7x - 70
7x - 3x = 70 - 10
4x = 60
x = 60/4
x = 15
The present age of Ram is 15 years.
The present age of his mother = 3(15) = 45 years.
We need to find their present ages.
Present of his mother = 3x years.
10 years before,
⇒ 3x - 10 = 7(x - 10)
⇒ 3x - 10 = 7x - 70
⇒ 7x - 3x = 70 - 10
⇒ 4x = 60
⇒ x = 15
