# 36 Men Can Complete a Piece of Work in 18 Days. In How Many Days will 27 Men Complete the Same Work?

### Computer MCQs Series for PPSC, FPSC – Most Repeated MCQs | Set 4

• 36 men can complete a piece of work in 18 days.
• Days required for 27 men to complete the same work can be figure out in this way.

## Explanation

Two given entities here are

1. Men
2. Days

To determine the relation here, let suppose; days required by 27 men to complete the job = y

Case

As we know that;

Men           Days

36               18

27               y

• Days decreases as men increases.
• Days increases as men decreased.

This clearly indicates that there is inverse relation.

Direct/Indirect relation tells how the equation will be written.

36 : 27  ::  y : 18 ________ (A)

After simplifying equation (A), we can easily figure out the value of y (y = 24)

## To Find

Days required by 27 men to complete the job = ?

## Solution

Method I

Let suppose

Days required by 27 men to complete the job = y

Men           Days

36               18

27               y

Relation between men and days is inverse, so;

36 : 27  ::  y : 18

36 x 18 = 27 x y

648 = 27y

24 = y

Days required by 27 men to complete the job = 24 days answer

Method II

36 men can do work = 18 days

1 man can do work = 18 x 36

1 man can do work = 648

27 men can do work = 648/27

27 men can do work = 24 days

Days required by 27 men to complete the job = 24 days answer

Conclusion

36 men can complete a piece of work in 18 days. 27 men will take 24 days to complete the job.
