The guest room department of a hotel has triple rooms and double rooms, and the charges are 150 yuan and 140 yuan respectively. In order to attract tourists, a 50% discount is implemented for group stays.

Half discount for group occupancy, then the actual room price is 75 yuan and 70 yuan for a triple room and a double room respectively.

Suppose X people stay in a triple room, then a double room is 50-X,

Then: the number of triple rooms is X/3, and the number of double rooms is 25-X/2

75X/3 70(25-X/2) =1510

Solution

X=24 people

Then: triple room and double room are 8 and 13 respectively
