Father is four times as old as Mary. Five years ago he was seven times as old. How old is the father now?

melamori03 [73]

Answer:

If Father is four times older than Mary, that would be 4 times 10-- which equals 40. Five years ago, Mary must have been 5 years old. So, multiply 7 and 5 and you'll get 35! Father would have been 35 years old.
