Question

10 people who build at the same rate can frame a house in 6 days. What fractional part of a house can 4 people frame a house in 3 days?

a. 1/2
b. 1/3
c. 1/4
d. 1/5
e. 1/6

Answer 1

10 people who build at the same rate can frame a house in 6 days. That means it will take one person
`10*6=60` days to finish the house.

Which means that it will take 4 people
`(60)/(4)=15` days to finish the house.

So, the fractional part of the house 4 people can frame in 3 days will be
`(3)/(15)=(1)/(5)`

Thus, Option D is the correct answer.
