Given :

33 workers can finish a job in 42 days.

To find :

The number of workers to complete the same job 66 days.

Solution :

In 42 days, no of workers required to complete the job = 33

In 1 day, no of worker required to complete the job = 33 x 42

In 33 days, no of workers required to complete the job = 33 x 42/66

=> 21 workers.

Hence,

66 workers are required workers complete the same job in 21 days. Ans

Answer 2

Answer:

Given

33 workers complete a job in 42 days.

To find

time taken by 66 workers to complete the same job.

solution

unitary method

☞The unitary method is a method in which you find the value of a unit and then the value of a required number of units

___________________________________

time taken to complete a job by 33 worker= 42 days.

Time taken to complete a job by 1 worker = 42 /33 days

By applying unitary method we get

time taken to complete a job by 66 workers =

$\bold{ \frac{42}{33} \times 66} \\ \\ ➥84 \: days$

So, 66 workers will complete their work in 84 days.
