Question

Thirty five workers build a house in 16 days. How many days will 28 workers working at the same rate take to build the same house

Answer 1

Answer:

28 workers will take 20 days to build the same building

Step-by-step explanation:

35 workers build a house in 16 days

28workers build a house in X days

now,

35×16= 28×X

X=35×16 35× 4 5×4

_____ = ______ =

28 7

X=20 days

Answer 2

Given:

Thirty-five workers finish work in 16 days.

To find:

To calculate the days required to complete the work by twenty-eight workers.

Solution:

We know the values of the number of workers and the number of days.

The formula used is,

(M₁× D₁)/ W₁ = (M₂ × D₂)/W₂

where M₁ and M₂ = total men

D₁ and D₂ = days

W₁ and W₂ = work done

Thirty-five workers build one house in 16 days.

M₁ = 35

D₁=16

W₁ = 1 (since one house is built)

Twenty-eight workers can build one house in D₂ days.

M₂ = 28

W ₂= 1 (since one house is built)

Putting values in the formula, we get,

(35×16)/ 1 = (28×D₂)/1

D₂ = 20 days

The total days required by twenty-eight workers to build one house is 20 days.
