Answer:
Step-by-step explanation:
Let the present age of father be x
And of child be y
Condition 1
X = 6y
x - 6y = 0 ........ (I)
X + 4 = 4( y+4 )
x + 4= 4y +16
x - 4y = 12 .......(II)
By elimination method
Substract EQ 1 from EQ 2
x - 4y = 12
x - 6y = 0
- - -
Therefore 2y =12
=> y = 6
Substituting the value of y in EQ 1
X =6y
Therefore x = 36
The Father age is 36 at present
& Sons age is 6
