Large rooms = 6

Step-by-step explanation:

Let the number of large rooms be x

Evelyn booked 2 more small rooms than the larger rooms.

Therefore the number of small rooms would be x+2.

Given each large room can accommodate 5 people.Therefore the total number of people in large rooms are 5x.

Given each small room can hold 3 people. Therefore the total number of people in large rooms are 3(x+2)

Total number of people accommodated = 54

Total number of guests = total guests in small rooms + total guests in large rooms

54 = 5x + 3(x+2)\\48 = 8x\\x = 6

No of large rooms = x = 6

No of small rooms = (x+2) = (6+2) = 8
