Question

A man is 4 times as older as his son , after 20 years he will be twice as old as his son at the time. find their present ages​

Answer 1

let the son's age be x

then father's age will be 4x

after 20yrs

(x+20)2=4x+20

2x+40=4x+20

40-20=4x-2x

20=2x

x=10

therefore son's age is 10 and father's age is 10×4=40
