Three men bought a loaf of bread for 30 naira. Because of their jovial nature, the woman-seller was happy with them and decided to give them 5 naira discount.
Since the men had left, she decided to send her daughter after them to return the money.
Believing that it would be difficult for three men to share 5 naira, the girl decided to give them 3 naira and pocket the remaining amount, which is 2 naira. So, she gave the men 1 naira each.
Thus, each man paid 10 naira and got 1 naira back. Paying 9 naira each means they paid 27 naira in all. The girl has 2 naira with her making 29 naira.
Where is the remaining 1 naira?
