B9D means B is the sister of D.
B4D means B is the brother of D.
B3D means B is the wife of D.

Which of the following means F isthe mother of K?

(1) F3M5K
(2) F5M3K
(3) F9M4N3K
(4) F3M5N3K​

Answer 1

I don't know the answer, but I can try and help using the information I do know

It is already stated that F and K represent the mother and child respectively. Thanks to the examples at the top, we know that 5 stands for parent, 9 stands for sister, 4 stands for brother and 3 stands for husband/wife. We can safely assume that the M represents the title of mother. Unfortunately, I have no clue what the N stands for. Using this information, we can start piecing together what the answers mean.

Let's use (1) as an example

This one says F is married to the mother of K, since 3 stands for partner and 5 stands for parent

Hopefully this helps in some way

Answer 2

Answer:

(1) F3M5K

Explanation:

F3M suggests that F is the wife of M.

M5K suggests M is the father of of K.

So, F will be mother of K.
