Answer 2

Answer:

$age \: of \: father \: is \: 55 \: years \\ \\ \: age \: of \: son = 30 \: years.$

Step-by-step explanation:

$age \: of \: father = x \\ \\ age \: of \: son = y \\ \\ x + y = 85 \\ \\ 3(x - y) = 75 \\ \\ x - y = 25 \\ \\ solving \: we \: get \\ \\ 2x = 110 \\ \\ x = 55 \\ \\ y = 55 - 25 = 30 \\ \\ the \: age \: of \: father \: is \: 55 \: years \\ \\ \: age \: of \: son = 30 \: years.$
