HARRY’S HUNDRED*
Harry has £100. He has split this money into seven envelopes each containing a whole number of pounds. Whatever number of pounds you want, between £1 and £100, Harry can hand you envelopes that in total contain that number of pounds. So, for example if you want £40, he hands you the envelopes that contain £32 and £8. How much is in the envelope that contains the most money?
