Question

A man is 4 times as old as hos son. After 16 years he will be only twice as old as his son. Find their present ages

Answer 1

Answer:

32 years

Step-by-step explanation:

Let Son's age =x and Man's age =4x

After 16 years,

2(x+16)=4x+16

2x+32=4x+16

16=2x

x=8 years

∴ Son's age =8 years and Man's age =32 years.

Answer 2

Suppose son's current age is x

And father's current age is y

And we can say y=4x

16 year latter son's age is x+16

And father's age is y+16= 4x+16

We can say,

2(x+16)=4x+16

Or, 2x+32=4x+16

Or, 16=2x

x=8
