Question

a man is six times as old as his son.twenty years later,the man will be twice as old as his son.find the age of the man when his son was born​

Answer 1

Step-by-step explanation:

let the age of the son is x

so age of the mam is 6x

after 12 years the son will be x+12

and man will be 6x+12

as per question,

6x+12 = 2 (x+12)

6x+12=2x+24

4x=12

x=3

so the man age is 6×3=18

so when his son was born he was (18-3)=15 years old.
