Answer 1

Answer:

The ratio of days in which they will complete the work is 20:15:12.

Step-by-step explanation:

Consider the provided information.

The same type of work is assigned to three groups of men the ratio person in the groups is 3 ratio 4 ratio 5.

As we know the number of days is inversely proportional to the number of person.

Thus, the number days is:

1/3: 1/4: 1/5

find the LCM of 3,4 and 5.

The LCM of 3, 4 and 5 is 60.

60/3: 60/4: 60/5

20:15:12
