Problema cu vaci

Proposed by IoMirceaOffline
(19 comments)10.691 times displayed

In 18 zile, 64 vaci pasc iarba unei pasuni de 48 ari. In 30 zile 84 vaci pasc iarba unei pasuni de 90 ari. Cate vaci ar putea paste iarba unei pasuni de 60 ari in 20 zile?

Atentie: nu e o problema de trei compusa. Nu uitati factorii "ascunsi" care pot influenta rezultatul :)
