Atley, bradley, cursen, and drake are the married names of kermit, leonard, marlene, and norma. read the clues to find each person's full name.

1. drake is bradley's sister.
2. cursen is atley's brother
3. norma and drake are not related
4. kermit is a year older than bradley

This is how the chart will look like:
              Kermit          Leonard           Marlene         Norma
Atley

Bradley

Cursen 

Drake

1. Drake is Bradley's sister.
2. Cursen is Atley's brother
3. Norma and Drake are not related
4. Kermit is a year older than Bradley

Drake is a girl (1), but she is not related to Norma(3), So she is Marlene.
1) MARLENE DRAKE

Drake and Bradley are related; Norma is not related to them(3). Norma can either be Atley or Cursen. But, Cursen is Male. So, Norma is NORMA ATLEY

Remaining family names are Bradley and Cursen. Kermit is not a Bradley, so he is KERMIT CURSEN. That leaves LEONARD BRADLEY.

 

Look at the picture. The numbers refer to why i said that this relationship is not possible and the yellow line means we alrady found this person, so we don't have to search anymore!

1) since Norma and Drake are not related, they can't be the same person.
2) If Bradley is related to Drake then he would be related to Norma- but they can't coz we know that they're not related! So Bradley and Norma are not related, and they can't be the same person
3) Kermit is a year older than Bradley - so they can't be the same person
4) let's look at the genders: Norma is female, and since Atley and Cursen are related, and Cursen is Atley's brother, then she must be Atley!!!

So we have one name: Norma Atley

Now, Drake must be the other woman: Marlene

5) - the only possibility we have left for Kermit now is Cursen! (since it can't be Bradly)

and we're left with Bradley Leonard!!!

The answer is 8 apex
