1 rumah = 15 x 20 = 300
1 rumah = 12 x n = 300
maka nilai n
300 = 12 x n
300 : 12 = n
25 = n
maka selama 25 hari
12 orang = x hari
Karena oini perbandingan berbalik nilai, maka :
15/12 = x/20
12x = 15 . 20
12x = 300
x = 300/12
x = 25 hari.
Jadi pemborong itu akan menyelesaikan pekerjaan nya selama 25 hari ==> E
