Question

The age of the father is twice the sum of the ages of his children After 20 years, his age will be equal to the sum of the ages of his children. Find the age of the father​

Answer 1

Step-by-step explanation:

let the age of the child be x

the age of the father is( x+x)=2x

ATQ:

after 20 yrs:2x=x

x=20/2=10yrs(child age)

father age=2x=2*10=20yrs

Answer 2

Step-by-step explanation:

in 20 years, the age of the father will be x + 20. in 20 years, the sum of the age of the children will be w + 40. this is because each child has aged 20 years, so the sum of the years the 2 children have aged is 40. you have 2 equations that need to be solved simultaneously
