At the birth of his sons. Ali's age is 32 and after how many years it's age become 5 times of his son's age?
- 6 years
- 8 years
- 10 years
- 12 years
Explanation
Ali's current age is 32.
His son's current age is 0 (newborn).
We want to find the number of years it takes for Ali's age to be 5 times his son's age.
Let's assume the number of years is x.
After x years, Ali's age will be: 32 + x
And his son's age will be: 0 + x = x
We want Ali's age to be 5 times his son's age, so we set up the equation: 32 + x = 5x
Subtracting x from both sides: 32 = 4x
Dividing both sides by 4: 8 = x
Therefore, it will take 8 years for Ali's age to be 5 times his son's age.
The correct answer is 8 years.
