c) A man is now 5 times as old as his son. In 8 years time, he will only be 3 times as old as his son. How old is the father now?

d) Dave is presently 20 years older than his daughter Alison. If Dave’s age 12 years from now is twice Alison’s age 12 years from now, find their present ages

e) I have some 20 cent coins and 5 cent coins in a box, totalling $2.55.. There are 6 more 5 cent coins than 20 cent coins. How many of each coin do I have?
