Three painters Ron, Victor and Shelly are painting the rooms of a hotel which are numbered from 15 – 200. Ron has to work in all the rooms. Victor has to work in rooms where the room number is a multiple of 3. Shelly has to work in rooms where the room number is a multiple of 5. In which rooms will they all work together?
Answers
Answer:
15,30,45,60,75,90,105,120,135,150,165,180and195
Step-by-step explanation:
Ron Will be present in all rooms
So, To find the rooms in which Shelly and Victor will come together we will take Common Multiple of 3 and 5
They are= 15,30,45,60,75,90,105,120,135,150,165,180and195
Answer:
Step-by-step explanation:
Rons Working room numbers are: 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25......
Victor's Working room numbers are: 15, 18, 21, 24, 27, 30, 33... ( Multiples of three)
Shelly's Working room numbers are: 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 (Multiples of 5)
So they works together in room numbers: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,( Which are the multiple of 3x5=15, and the numbers will be multiple of 15 but greater or equal to 15 and less than 200
