30 afirmatii

Proposed by GabiOffline
(one comment)1.542 times displayed

Profesorul scrie un numar natural nenul n si le cere celor 30 elevi sa indice divizori proprii (si neaparat distincti!) ai acestui numar n. Primul elev declara ca n se divide cu 2. Urmatorul spune ca n este divizibil cu 3, samd, pana la al 30-lea, care spune ca n se divide cu 31.
Doua din cele 30 de afirmatii facute de elevi sunt false. Cele 2 afirmatii false au fost facute consecutiv.

Gasiti-le.
