One day, when Little Red Riding Hood was visiting Granny, she asked, “Granny, how old are you?”
Never one to give a straight answer, Granny replied, “I have 7 children, my dear, and there are 3 years between each one and the next. I had my first child when I was 23. My youngest child is 23 herself now.”
How old is Granny?
If the last child is now 23 and Granny had her when she was 41 (41 + 23) that means that Granny is 64.
