Question

The sum of the present ages of a father and his son is 40 years. Four years hence
father will be three times as old as his son will be. Find their present ages.​

Answer 1

Answer:

present age of son is 13 and father is 27

Step-by-step explanation:

let the present age of son be x and father be y

x+y=40

=> y=40-x ------(i)

after 4 years

y+4=3(x+4)

y+4=3x +12

from (i)-

40-x+4=3x+12

4x=52

x=13

y=40-13=27

present age of son is 13 and father is 27
