Answer:
The question is wrong. This is my explanation why the question is wrong.
Let son's age be x.
Then, father's age=4x.
After 17 years:
father's age=17+4x
Son's age is=17+x
father's age is 2 times. the age of his son, that is:
17+4x=2(17+x)
17+4x=34+2x
17-34=2x-4x
-17=-2x
x=17/2
sum of their ages is 56, that is,
17+x+17+4x=56
34+5x=56
5x=56-34
x=22/5
- All the values of x should be equal, but it is not.
- the value of X is not a whole number.
thus, question is wrong.
