Let number of already existing houses = 100
New established = 300
60% of already existing houses = 60
76% of new established houses = 76*3 = 228
total house sold = 228+60 = 288
Percentage = (288/400 ) * 100 = 72%
New established = 300
60% of already existing houses = 60
76% of new established houses = 76*3 = 228
total house sold = 228+60 = 288
Percentage = (288/400 ) * 100 = 72%
