At present, there are two tour groups, Party A and Party B. If tickets are purchased separately, the two groups should pay 1 166 yuan. If two groups buy tickets together, they need 880 yuan. How many people are in each group? Solution: let the number of people in a group be x,

Then (880/8-x) *10+12x =1166.

The solution is x=33,

So 880/8-x=77

A: There are 33 people and 77 people in the two groups respectively.

Analysis: 880 yuan was used by two groups of people to buy tickets together, indicating that the number of people in the two groups exceeded 100 (because if the total number of people did not exceed 100, then the money for buying tickets together was less than 100 * 8, that is, 800 yuan), so their total number was 880/8 =1650. Let the number of the smaller group be x, and the number of the larger group be (1 10-x), that is, the above-mentioned (880/8-x). Further analysis, if the number of people in the two groups is between 50 and 99, then the fare of each ticket they buy is 10 yuan, so the total * * needs 110 *10 =1100 yuan, but
