pradeep receives an export order for garments. he has 30 machines to complete the order in 60 days. how many machines would be required to complete the job in 40 days?a. 50

Answer 1

30 machines takes 60 days.

1 machine takes 30*60 days = 1800 days.

Let the no. of machines required to do the job in 40 days be x

x=1800/40 = 45

45 machines complete the job in 40 days.

Answer 2

Answer:

The correct answer to the given question is 45 machines required to complete a job in 40 days.

Step-by-step explanation:

Given data :

Pradeep receives export orders for garments.

30 machines are required to complete the order in 60 days.

To find:

How many machines are required to complete the job in 40 days?

Solution:

Based on the question it is observed that the number of machines is inversely proportional to the job done in the number of days.

The inversely proportional resembles with more machine, fewer days

fewer machines more days of work.

firstly we have to find the number of machines required to complete the work in one day.

$60days = 30machines$

$1 \: day \: = 60 \times 30 = 1800machines$

for one day the number of machines required is 1800.

the number of machines requires to complete a work in 40 days is

$\frac{1800}{40} = 45$

Therefore,45 machines are required to complete a job in 40 days.
