My sister is three years younger than my brother and three years older than i am. my mother is the sum of our ages. My sister is 15 years old,and my mother is two years younger than my father. How old is my father

Respuesta :

It was a little confusing but... first you take the sisters already given age then for the brother add 3 years so the brother is 18. then subtract 3 from 15 to get "my" age which is 12. then add 15,18 and 12 for the moms age and you get 45. then add 2 years for the father and his age is 47 years old. Hope it helps!!
