How many houses are left

Apr 7th, 2015

Total number of houses built = 42

number of houses sold last month = 42 * 2/3

                                                        = 28

Remaining houses = 42 - 28

                               = 14

Houses sold in remaining houses = 14 * 3/7

                                                       = 6

Number of houses left = 14 - 6

                                     = 8
