Am 13 bancnote a cate 5lei fiecare. Imi cumpar o pereche de pantofi si imi mai raman cu 6 bancnote . Cati lei mi-ar fi ramas as fi avut 6 bancnote a cate 10 lei si as fi cumparat aceeasi pereche de pantofi ?

Answer 1

13*5lei=65(lei am avut)
13-6=7(bacnote am folosit pentru pantofi)
 7*5lei=35(lei au costat pantofii)
 6*10lei=60(lei as fi avut)
 60lei-35lei=25lei(lei mi-ar fi ramas)
