Question

Three persons can build a small house in 8 days. To build the same house in 6 days,how many persons are required?

Answer 1

Persons required to build house in 8 days =3
Persons required to built house in 1 day =3×8
Persons required to built house in 6 days = (3×8)/6
= 4 persons

Answer 2

Answer:

4 persons are required to build the same house in 6 days.

Step-by-step explanation:

It is given that three persons can build a small house in 8 days.

Total work is done is

$W_1=8\times 3=24$

Let the same house can build by x person in 6 hours.

Total work is done is

$W_2=6\times x=6x$

$W_1=W_2$

$24=6x$

Divide both sides by 6.

$4=x$

Therefore, 4 persons are required to build the same house in 6 days.
