Question

a man is 4 times as old as his son. after 16 years he will be only twice as old as his son.find their present ages.​

Answer 1

Let mans age be m and sons age s

Therefore
m=4s
m+16 = 2(s+16)

Substitute eq 1 in 2

And

4s+16=2s+32
2s=16
S=8

S=8 in m=4s

Therefore m=32

Father is 32 years and son is 8 years
