At the Huxtable household, Valentine's Day is a special day. Mother Claire kicks off the holiday a week early byÂ secretly assigningÂ each of her five children the job of sending a valentine card toÂ one other sibling. She makes the assignments herself, but asks the kids to keepÂ quietÂ until the five cardsÂ are delivered. SheÂ even takes the time to ensure that the sender ofÂ each card doesn't receive a card from that same sibling. What a mom, huh?
Anyway, you probably know the names of theÂ Huxtable brood. Sondra is the oldest, followed by Denise, Theo, Vanessa, and little Rudy. Given the above information and these three clues, can you determine the senders and recipients of each of the five valentine cards?
1. Theo sentÂ his valentine to a sibling older than he.
2. Sondra's valentine went to one of the two youngest Huxtables.
3. Denise, who did not send aÂ valentine to Vanessa, thanked Rudy for hers.
Here is the SOLUTION.
Rudy sent a valentine to Denise;
Vanessa sent a valentine to Rudy;
Theo sent a valentine to Sondra;
Denise sent a valentine to Theo; and
Sondra sent a valentine to Vanessa.
Clue #1 indicates thatÂ Theo sent a valentine to either Denise or Sondra.
Clue #2Â reveals thatÂ Sondra sent a valentine to either Rudy or Vanessa.
According to clue #3,Â Denise did not send Vanessa's valentine. Also, Rudy sent Denise's valentine.
By elimination, Theo sent Sondra's valentine.
Since Rudy sent Denise's card, Denise could not have sent Rudy's valentine; so Denise'sÂ card went to Theo.
Vanessa could not have sent a valentine to herself, so hers went to Rudy, and Sondra's went to Vanessa.
