If the age of lrfan's father is three times more than that of Irfan's and the sum of ages (in years) of both people is equal to the perfect square of 8, then what will be the age of lrfan?
- 18 years
- 17 years
- 16 years
- 24 years
Explanation
The sum of the ages (in years) of both people is equal to the perfect square of 8.
So, a perfect square of 8 = 64.
Therefore, the sum of ages (in years) of both people = 64 years.
Now,
Let, the age of Irfan's be x.
Then, the age his father's be 3x.
According to the question :
➮ x + 3x = 64
➮ 4x = 64
➮ x = 64/4
➮ x = 16.
