Question

168 men can do a piece of work in 14 days, how many men will do the same work in 42 days? show ur solution.​

Answer 1

Answer:

56 men

Step-by-step explanation:

168 men --> 14 days

1 men = 1/(14*168) days = 1/2352 days

2352 men --> 1 day

42 days --> 2352/42 = 56 men

Answer 2

Given:

168 men can do a piece of work in 14 days.

To Find:

In 42 days, how many men can complete the same task?

Solution:

Let m represent the number of men required to complete the task in 42 days.

The formula that is used to find the required value is $\frac{M_1D_1H_1}{W_1}=\frac{M_2D_2H_2}{W_2}$. Here, M, D, H, and W represents the number of men, days, hour, and work done by men and women.

From the information in the question, formulate an equation.

$168\times 14=m\times 42$

Simplify the obtained expression.

$\frac{168\times 14}{42}=m\\ 56=m$

Thus, 56 men are required to complete the task in 42 days.
