Answer 1

Answer:

canteen a = 12

canteen b = 8

canteen c = 10

all three together the will meet...

we can find this by finding the LCM of 12,8 & 10

Find the attached file for it... (after viewing)

LCM = 2x2x2x3

        = 24

so all will serve noodle soup on the 24th day.

Answer 2

Answer:

After 120 days all the three canteens will serve noodle soup again

Step-by-step explanation:

LCM = 2 x 2 x3 x 2 x 5

= 120

LCM (12, 8, 10) = 120
