80 1/2 days between first and second son

This in days is 1-81 days to finish one house.

Step-by-step explanation:

1st Son  = 45 + 18 + 27 = 90  saved the father 18 days. 27 of 45 = 60% inv 40%

2nd Son  = 45 + 9 +36 = 90 saved the father 9 days = 36 of 45 = 80% inv 20%

1st Son  40% needs to be increased 60% to complete house

2nd Son  20% needs to be increased 80% to complete house

1st Son  House takes Son 1 in days =  27 x 1.60% = 43.2 + 27 = 60.2

2nd Son House takes Son 2 in days = 36 x 1.80%= 64.8 + 36 = 100.8

60.2+100.8 = 161 days.

=161 days for 2 homes.

= 80 1/2 days for one home.
