Question

76 persons can complete the job in 42 days. In how many days will 56 persons do the same job?​

Answer 1

Answer:

good question I write and tell

Answer 2

Answer:

57 days

Step-by-step explanation:

Let the number of day taken by 56 persons to finish the same job be x

Now, in tabular form we can see

No of Persons 76 : 56

No of days 42 : X

Here number of people is decreased therefore time will be more, and we know that when one quantity increases and another quantity decreases, it is a case of Inverse Variation, according to which:

76 × 42 56 × x

x = (76 x 42) / 56

x = 57

56 persons will take 57 days to finish the same job.
