Question

If 15 workers could finish the work in 42 hours how many workers are required to finish the same work in 30 hours

Answer 1

Answer:

21 is the write answer of the question

Answer 2

Number of workers = C/hours (here “C” is the constant of proportionality)

Now, consider the first case: “15 workers can finish a task in 42 hours”

Here, 15 = C/42

=> C = 15 × 42 = 630.

Now, consider the second case: “x workers can finish a task in 30 hours”

Here, x = C/30

=> x = 630/30
