Question

Fathers age is three times the sum of ages of his two children.After five years his age will be twice sum of ages of two children .find the age of father

Answer 1

Answer:

45

Step-by-step explanation:

Lets us assume fathers age =x

two children ages be x and y then

x=3(y+z)....eq1

y+z=x/3

After 5 years

(x+5)=2(y+z+10)...eq2

solving eq1 and eq2

x+5= 2x/3+20

2x/3-x = 5-20

-x/3=-15

x=45
