Answer:
120 days
Step-by-step explanation:
Canteen A = 12 days
Canteen B = 8 days
Canteen C = 10 days
How many days later will all three canteen serving noodles soup again?
To find the number of days all 3 canteens will serve food again, find the lowest common multiples of all 3 canteens
Canteen A = 12 days
34, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Canteen B = 8 days
16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120
Canteen C = 10 days
20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130
The lowest common multiple of 12 days, 8 days and 10 days is 120 days
The next day all 3 canteens will serve soup together again is the next 120 days
