<image>A website published a random sampling survey on housing purchase demand for the fourth quarter of 2004. Below is a bar chart showing the proportion of housing groups that can accept various price ranges (the price range a~b means greater than or equal to a but less than b).

Based on the information provided in the bar chart, please answer the following questions:
(1) What is the acceptable price range for the group with the highest proportion among the housing groups?
(2) What proportion of the housing groups can accept a price range of less than 5000 yuan per square meter?
(3) If the number of people with housing purchase demand in the fourth quarter of 2004 is 60,000, estimate the number of people among them who can accept a price of 10,000 yuan per square meter or above.
