arithmetic - 5 years ago arun was three times as old as his daughter and 10 years hence he will be two times as old as his daughter then aruns current age is - skillgun

Arun’s age = A and
daughter’s age =B
Then, A – 5 = 3(B – 5)
=> A – 3B + 10 = 0 ……(1)
And, A + 10 = 2 (B + 10)
=> A – 2B – 10 = 0 ……(2)
Solving the 2 eqns, we will get
A = 50, B = 20.
Therefore,
Arun’s age is 50
And his Daughter’s age is 20
