My son is 1/3 my age now.Five years ago,he was 1/4 my age then.How old is my son?
No need now thanks everyone.
*In case you need the answer,it is 40.
Right now: My son is X yrs. old.
My age = 3x years old.
Five yrs. ago:
My son's age: x-5.
My age: 3x-5.
3x-5 = 4(x-5).
3x-5 = 4x-20
X = 15 = My son's age now.

To find out how old your son is, we can set up an equation based on the given information.
Let's say your current age is represented by "x" and your son's current age is represented by "y". According to the information given, we know that:
1) Your son is currently 1/3 of your age: y = (1/3)x
2) Five years ago, your son was 1/4 of your age: y - 5 = (1/4)(x - 5)
To solve this system of equations, we can use substitution or elimination.
Using substitution, we substitute the value of y from equation 1) into equation 2):
(1/3)x - 5 = (1/4)(x - 5)
Now, we can solve for x:
Multiply both sides of the equation by 12 to eliminate the fractions:
12[(1/3)x - 5] = 12[(1/4)(x - 5)]
4x - 60 = 3(x - 5)
4x - 60 = 3x - 15
Subtract 3x from both sides:
4x - 3x - 60 = -15
x - 60 = -15
Add 60 to both sides:
x = -15 + 60
x = 45
So, your current age is 45.
Now, substituting this value back into equation 1) to find your son's age:
y = (1/3)(45)
y = 15
Therefore, your son is currently 15 years old.
