Question

(3) The sum of father’s age and twice the age of his son is 70. If we double the age

of the father and add it to the age of his son the sum is 95. Find their present ages. ​

Answer 1

AGE OF FATHER IS -40YEARS

AGE OF SON IS -15 YEARS

Answer 2

Answer:

let father's age be x yrs

and son's age be y yrs

condition 1

x=2y

x+2y=70.......1.....×2

condition 2

2x+y= 95......2

2x+4y=140.....3

subtract 2 from 3

2x+4y=140

2x+y= 95.

-----------------

3y= 45

y=15

put in 1

x +2y= 70

x+30=70

x= 40

father's age is 40yrs and son's age is 15 yrs
