Question

Four boys in the class sent a valentine to a different girl. Henry didn’t send one to Annabel, but Billy sent one to either Mary or Deborah. Mary didn’t get a card from John or Greg. Neither John nor Greg sent a card to Harriet. Greg would NEVER send a card to Annabel! Who sent a valentine to Annabel?

Answer 1

John is the answer....

Answer 2

Let me try to answer this.

From the challenge, the one who sent the letter to Annabel is John. Because we are told that Henry did not send the letter to Annabel, Billy sent but he send to either Mary or Deborah, Mary did not get from both John and Greg,But it is insisted that greg could not sen Annabel the letter. it is therefore evident automatically that John is the sender of the letter to Annabelle
