Question

There are 60 new houses being built in a neighborhood. Last month, 1/4 of them were sold. This month, 1/5 of the remaining houses were sold. How many houses are left to be sold.

Answer 1

36

Explanation:

Number of new houses = 60

Number of houses sold last month = (1/4) of 60

`= (1)/(4)*60`

= 15

Remaining houses = 60 - 15 = 45

Number of houses sold this month = (1/5) of 45

`=(1)/(5)*45\\\\= 9`

Number of houses that are left = 45 - 9 = 36
