Q: Think of a familiar brand name ending in the letters G-S. Change the G-S to an O and you'll get the brand name of a different product. What is it? Hint: The first word has five letters, and the second has four.I had more familiarity with the second term so I solved it backwards. My wife had no problem solving it forward.
Edit: Both of us had this as soon as we finished reading the question. Hopefully you found it as simple.
