Firstly, the prime factor of 207025 is decomposed. Because everyone is a chicken, the difference of numbers is a multiple of 12, so there are two people who can get 1, two people who have 13, 25-year-old people have 1, and 49-year-old people have 1.
There are 49, and so are the zodiac signs.
Their age is 25, 13, 13, 1,
∵49+25+ 13+ 13= 100,
∴ 102- 100=2,
∴ There are 2 persons with age 1, 2 persons with age 13, 1 person with age 25, 1 person with age 49, ***6 persons.
