Long-term goals or a short-term goals, aim to meet them all.
Let,
The age of arun and his father be X and Y respectively…
According to I st condition,
Y = 4X (I)
According to II nd condition,
Y + 8 = (X + 8)×2
Y + 8 = 2 X + 16 (II)
By putting ,
Y = 4X in eq^n (II)
4X + 8 = 2X + 16
4X - 2X = 16 - 8
2X = 8
X = 4 yrs..
By putting X=4 in eq^n ( I )
Hence,
The age of father = Y = 16 yrs..
The present age of arun’s father is 16 yrs..

Let Arun’s present age be x and his Father’s present age be y. Given:
y = 4x
After 8 years, Arun’s age will be x+8 and his Father’s age will be y+8. Given:
y+8 = 2(x+8)
Solving these two gives:
Father’s age, y = 16
Arun’s age, x = 4
Now what really scares me is the fact that Arun’s Father became a dad when he was 12.
3-in-1 protection for moms-to-be helps protect baby too.
Let us assume the present ages of father and son be X and Y
X=4Y
After eight years
X+8=(Y+8)*2
X+8=2Y+16
Subsituting equation 1 with equation 2
4Y+8=2Y+16
2Y=8
Y=4
X=16
Present age of father is 16.( pretty young he he)
Let the age of the father be y
Let the age of arun be x
[math]y = 4x...1[/math]
[math]y+8=2(x+8)...2[/math]
Solving equaltions 1 and 2 will give
x = 4 , and y = 16.
