Hai vòi cùng chảy vào một bể sau 10h sẽ đầy, nếu mở vòi 1 trong 6h rồi khóa lại và mở vòi 2 trong 3h thì đầy 2/5 bể. Hỏi nếu mở riêng mỗi vòi sau bao lâu sẽ đầy bể

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
