If M + N means M is the sister of N.

M - N means M is the brother of N.

M x N means M is the daughter of N.

which of the following shows the relation that X is the maternal uncle of Y, where X's gender is male ?

Decoding the Symbols:

Given: X's gender is male

Now, checking options one by one:

• Option - (1): Y × Z + X → Y is the daughter of Z who is the sister of X.

Here, X is either the maternal uncle of Y.

• Option - (2): Z × X + Y → Z is the daughter of X who is the sister of Y.

Here, X is the sister of Y.

• Option - (3): Z × X - Y → Z is the daughter of X who is the brother of Y.

​

Here, X is the brother of Y.

• Option - (4): X × Z + Y → X is the daughter of Z who is the sister of Y.

Here, X is the niece of Y.

So, out of all the options 'Y × Z + X' is the only possible case that represents X as the maternal uncle of Y.

Hence, the correct answer is "Option - (1)".
