When my teacher was asked about his age, he answered:
“My age number is a prime number*, but if you reverse the digits the new-formed number can be divided by 5. Moreover, I wish I live up to this age”.
Can you find my teacher’s age?
*prime number is a number that can be divided only by 1 and itself e.g. 11 is divided only by 1 and by 11.
Όταν ο δάσκαλός μου ρωτήθηκε για την ηλικία του, απάντησε:
«Η ηλικία μου είναι πρώτος αριθμός αλλά, αν αντιστραφούν τα ψηφία διαιρείται με το 5 και ελπίζω να ζήσω τόσα χρόνια».
Πόσων χρονών είναι ο δάσκαλος;
