Answer 2

To find the answer to this question, we can use the concept of the work rate. The work rate tells us how much work is done in a unit of time. In this case, we are given that 5 men can build a house in 26 days.

Let's denote the work rate of 5 men as W5. Therefore, W5 = 1 house / 26 days.

Now, we need to find the number of days it would take for 10 men to build the same house. Let's denote the number of days it takes for 10 men as D10.

Since work rate is the amount of work done per unit of time, we can say that the work rate of 10 men building the same house is twice the work rate of 5 men. Therefore, W10 = 2 * W5.

We can substitute the values of W5 and W10 into the equation and solve for D10:

D10 = 1 house / W10

D10 = 1 house / (2 * W5)

D10 = 1 house / (2 * (1 house / 26 days))

D10 = 1 house * (26 days / 2)

D10 = 13 days

Therefore, the correct answer is B. 13 days.

Answer 3

man-days needed = 5(26) = 130

So 10 men should be able to it in .....

13?

130 / 10

To find the answer to this question, we can use the concept of the work rate. The work rate tells us how much work is done in a unit of time. In this case, we are given that 5 men can build a house in 26 days.

man-days needed = 5(26) = 130
