From Frédéric:
Bonjour, je me permet de vous envoyer un "petit" problème mathématique car je suis très mauvais même pour de très simples opérations comme celle qui va suivre!(lol). Si vous pouviez m'aider cela m'éviterai beaucoup de recherches inutiles. Voici le problème : une personne a placé 117180 en banque et cette somme lui rapporte tous les trimestres 936 d'intéret. Premièrement, peut on connaître le taux d'intéret ? Et deuxièmement, combien lui rapporterai, en intéret, la somme de 97180 ? Merci d'avance pour votre aide.
