Hi
Please could someone shed some light on today's puzzle. The clue is as follows:
At a charity dinner, the first 30 people to purchase raffle tickets had an average of three each. After a further 30 people bought tickets, the average number rose to eight. What was the average number of raffle tickets purchased by each of the last 30 people only. Is the answer 13?
Thanks
