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
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
