Answer:
The present age of son is 7
Step-by-step explanation:
Let the son age be x
One year ago
Son's age = x - 1
Therefore man's age = 8(x-1) =8x - 8
Now man's age = x^2
Difference between both ages if man =1 years
So
x^2 -(8x-8) = 1
x^2-8x + 8-1 =0
x^2- 8x + 7 = 0
x^2 - 7x -x + 7 = 0
X(x-7) - 7 ( x - 7) = 0
(x - 1) ( x - 7) = 0
x = 1, 7
But son cannot be 1 years
Therefore ,
x = 7
SO,
age of son is <em>7</em>
age of father is x×7=<em>49</em>
