Solution: It turns out that Xiao Li has 7 more flowers than Xiao Ming. After Xiao Ming has 2 fewer flowers, Xiao Li has 7+2=9 more flowers. After Xiao Li has three more flowers, Xiao Li has 9+3= 12 more flowers than Xiao Ming. At this time, Xiao Li's safflower is three times that of Xiao Ming, that is, 3- 1=2 times more. According to the strategist, Xiao was found at this time.

(7+2+3)÷(3- 1),

= 12÷2,

=6 (flowers),

Xiaoming: 6+2=8 (flowers),

Xiaoli: 8+7= 15 (flower),

A: Xiaoming originally spent 8 flowers, and Xiaoli originally spent 15 flowers.

Comments:

The test site of this question: the time difference problem.

Test center comments: The key to solve this problem is to determine the unit "1", and then find out the number of safflower of Xiaoli, which is more than that of Xiaoming, and the multiple of Xiaoli, that is, the number of safflower of Xiaoming.
