Question

If 104 men can do a peice of work in 70 days in how many days 28 men will do it

Answer 1

The number of days required to complete the work with 28 men is 260 days.

Given:

104 men can do a piece of work in 70 days

To find:

How many days will be required to complete the work with 28 men

Solution:

Given that 104 men can do work in 70 days

We need to number of days to complete the same work with 28 men  

Here if the Number of men decreased then the number of days to complete the work will increase, which shows that

The number of days and men are inversely proportional to each other  

The above relation can be represented in the ratio of

=> 104: 28 = x : 70

=>  $\frac{104}{28} = \frac{x}{70}$              [ do cross multiplication ]

=> $104\times 70 = 28 \times x$  

=>  $7280 = 28 \times x$  

=> $x = \frac{7280}{28}$              

=> x = 260  

Therefore,

The number of days required to complete the work with 28 men is 260 days.

Answer 2

Answer:

The final answer is 260 days.

Step-by-step explanation:

Given,

We have 104 men who can do a piece of work in 70 days. We need to find the amount of days it takes for 28 men to complete it.

Total amount of men it takes to complete the work in the First set = 104

Total amount of time it takes to complete the work in the First set = 70

Total amount of men it takes to complete the work in the Second set = 28

Total amount of time it takes to complete the work in the Second set = x

x * 28 = 104 * 70

x = 70 * 104 / 28

x = 2.5 * 105

x = 260
