Question

One carpenter builds 1/5 of a house in 3/4 of a day and the other builds 2/5 of a house in the same amount of time. How many houses do the two carpenters build in total per day?

Answer 1

The two carpenters build in total per day 4/5 of a house

Explanation:

we know that

One carpenter builds 1/5 of a house in 3/4 of a day

Other carpenter builds 2/5 of a house in 3/4 of a day

so

The two carpenters builds (1/5+2/5) of a house in 3/4 of a day

using proportion

Find out how many houses the two carpenters build in total per day

`((3/5))/((3/4))(house)/(day)=(x)/(1)(house)/(day)\\\\x=(4)/(5)\ of\ a\ house`
