1. Answer:

   Father: 30

   Son: 10

   Step-by-step explanation:

   Equation:

   If the son’s age is y, then,

   y + (y + 20) = 40

   2y + 20 = 40

   2y = 40 – 20

   2y = 20

   y = 20 / 2

   y = 10

   So the son’s age is 10.

   If the son’s age is 10, then,

   10 + 20

   = 30

   Hence the father’s age is 30.

2. Answer:

   Father = 30 years

   Son = 10 years

   Step-by-step explanation:

   Q. Father is 20 years older than son, sum of their ages is 40 years, so what are the ages of them.

   Solution –

   If we consider son’s age as x

   so father’s age will be x + 20

   sum of both ages = 40

   => x + x + 20 = 40

   => 2x + 20 = 40

   => 2x = 40–20

   => 2×x = 20

   => x = 20÷2

   => x = 10

   Hence son’s age = x = 10 years

   Father’s age = x + 20 = 10+20 = 30 years

   hope it helps.
