Joana have 3 sons january febuary and march whos the 4th one ?

answer well

1st Son = January

2nd son = February

3rd son = March

( Then simply )

4th will be May .This question is usually written a different way. It usually goes something like this. Bob’s mom has five kids. The First one is named January, the second one February. the third one March, the fourth one April, what is the fifth one’s name? Of course then the fifth one’s name is Bob. The way you have stated the question the fifth child might be named May, or it might be named Bob or anything else as we aren’t given any more information about the fifth child and there is no certainty that the mother would have stuck to the pattern in naming,
