ایک باپ اپنے بیٹے سے 5 گنا بوڑھا ہوتا ہے، 15 سال میں باپ اپنے بیٹے سے دگنی عمر کا ہو جاتا ہے؟ باپ کی عمر اس وقت کتنی ہے؟
- 20 years
- 25 years
- 30 years
- 35 years
Explanation
Let the son's age be x.
Then the father's age is 5x.
In 15 years, the son's age will be x+15
the father's age will be 5x+15.
According to the problem, in 15 years the father will be twice as old as his son:
5x+15 = 2(x+15)
3x = 15
x = 5
Therefore, the son is currently 5 years old.
The father's current age is 5 times that, which is 25 years old.
