Question

a father told his son my age is four time ur age . when u will be of my age then my age will be 9 years less than the twice of ur age...

plz give me solution fast ​

Answer 1

Step-by-step explanation:

let son's today's age be x years

so father's today's age be 4x

now when son becomes father's age

I.e. x becomes 4x means x increases by 3x

then father also increases by 3x years

so father becomes 4x+3x=7x years old

condition

father's future age = 2 * son's future age - 9

7x = 2*4x - 9

8x -7x =9

x = 9 years

so son's today's age 9

father's today's age 9*4=36 years
