* Maternal uncle means mother's brother
* Here P must b a mother's brother of Q i.e P is a maternal uncle of Q.its given in question
* P-M+N*Q - means brother, + means mother, * means sister
* Now its clear P is the brother of M & q is the child of m,so p relates to q is maternal uncle

p (brother)-> M (mother) -> n & q

hope u all understand :-)

It's most interesting question in alover the set. I liked it very much and it is a wonderful website.

Anu said: (Jan 8, 2011)  
Lets move from back. N and Q are sisters. Now both N and Q are daughters of M. Clear!. P is brother of M. i.e., if you are the child then your mothers brother is the paternal uncle.

Shivani said: (Aug 19, 2011)  
Nice explanation mytyli sister. Thanks.

Arun Ck said: (Sep 15, 2011)

Amit said: (Oct 28, 2011)  
Everyone here is just explaining the given answer but how did you got that ans? can any one tell me?

Ravi Bhatia said: (Nov 11, 2011)  
Analyze all options and classify all(PQRS etc) as per generation. for generation see introduction (below link)
(+ M, -B, %F, XS)
now first option Q - N + M x P
Q is brother of N means Q & N are from same generation.
N is the mother of M means M is next generation, and M is sister of P. It means M & P is from same generation.
separate lines for each generation
now if you analyze above it shows Q is maternal uncle of M&P hence rejected.

now second option P + S x N - Q (+ M, -B, %F, XS)
here relation is P is mother of SNQ rejected.
fourth option
Q - S % P
Q S , conc p is father of Q,S
now third option.
P - M + N x Q (+ M, -B, %F, XS)

P M , PM are brother sister, their mother is N and her brother is N hence this option is rit.
Further in above question + and % is separate generation.
- and x is separate generation.

Hello Friends,

Can you anyone explain me the clear idea about this type of relational sums? Because this is major problem for me. So much of confusion. Please help me!

Anshu said: (Mar 31, 2012)  
@ ariharan.

I would like to suggest something always try to make diagrams relating to blood relation problems. I always look forward to it. Hope you would like it.

Shminderjit Singh said: (May 13, 2012)  
1) Take it logically.
2) Let see the options.
3) All we want p on left side(as P is gona be related with Q) and Q on rite side.
4) Also we want * with Q on right side as he is P's mothers brother. Because brother sister relation is shown by * sign.
5) All this pointed toward option C.
6) Make family tree of c.
7) There u got the answer.

Arya said: (Sep 6, 2012)  
Someone tell me whatz the difference between maternal and paternal?

Baji said: (Oct 2, 2012)  
Maternal means mother's relatives paternal means father's relatives.

Latha said: (Jul 29, 2013)  
P - M + N x Q, when we use the arithmetics , here why you are not taking the negative sign for M, while you are relating with M with N , when we use in mathematics we do as N-M so do explain, also you are dividing each then Y? we should use the signs.

Shahid said: (Sep 15, 2013)  
I don't understand anything, will anyone please help me, is any shortcut of these type of questions.

Ankit said: (Oct 21, 2013)  
Can anyone please tell me short trick or give these type of answer fastly?

Srikantini Achary said: (Nov 14, 2013)  
Why use other alphabet?

Pratish Patil said: (Jan 28, 2014)  
Look at the options in A and D option we don't know the gender of P so leave it for moment look at option B here P is female cause P+S so leave it, now in option C start from left * mean Q's sister then + mean Q's sister mother . i.e mean Q's mother. Then - means Q's mother brother i.e maternal uncle.

Remember always start from left.

Shubham Arora said: (Feb 9, 2014)  
What say about option A?

I think its same as that of option C?

Arun N said: (May 3, 2014)  
If C is the answer means then what is the difference between option A and C?

Samir Kumar Das said: (Dec 18, 2014)  
It was very simple.

1st see which option start form "P" ->

[B]. P + S x N - Q.
[C]. P - M + N x Q.

Start with option B = P + S = P is the mother of S = wrong equation.

Start with option C = P - M = P is the brother of M.

M + N = M is the mother of N.
N * Q = N is the sister of Q.

Q. Which of the following shows that P is the maternal uncle of?


Kane said: (Jan 8, 2015)  
If p is the father of q and s is the mother of t then who is the granny of f?

Frogslegs said: (Feb 5, 2015)  
I got the answer to the question. But I don't see why you need the * bit in the answer. Shouldn't it just be P-M+Q as Q is the child of M and P is the brother of M, making P the maternal uncle of Q. It is surely a more correct way of putting it?

Ananya said: (Feb 16, 2015)  
Why can't it be P-M+Q?

Akash said: (Apr 4, 2015)  
Can anybody draw the diagram?

It Tharun said: (Jun 4, 2015)  
N''-----> Q.

Friends mostly this kind of questions option is A or A option values change means in place of Q he give P and in place of P he give Q like that.

Manju said: (Oct 5, 2015)  
The answer could just be->P-M+Q.

Shah Fayaz said: (Oct 9, 2015)  
I don't know, why alphabets are changed in answers?

Please explain me.

Prashant said: (Oct 9, 2015)  
Any shortcut?

Adeesh said: (Nov 23, 2015)  
Have anybody any formula for this type of question?

Hamidullahhamidi said: (Feb 25, 2016)  
a+b = a mother of b.

a-b = a brother b.

a%b = a father b.

a*b = a sister b.

p maternal uncle of q = ?

q-n = q brother n.

n+m = n mother m.

m*p = m sister p.

(m sister p) daughter of n (n is brother q) here (q is maternal uncle p) opposite to the question. So not correct.

p+s = p mother of s.

s*n = s sister of n.

n-q = n brother of q.

Here (s, n, q are brother and sister) and their (mother is p). So not correct.

p-m = p brother of m.

m+n = m mother of n.

n*q = n sister of q.

Here (n and q sister) their (mother is m) and (p and m) are brother and sister (brother of m is maternal uncle of q). So it is correct answer.

I didn't understand it, can you please explain me clearly ?

Ragul said: (Jun 28, 2016)  
Hi, I didn't understand this topic, please help me!

Poonam said: (Jul 14, 2016)  
Can't understand this, help me to get it.

Snigdha said: (Jul 24, 2016)  
P - M + N * Q. According to above relationships between A and B given in the question.

Just follow. P - M = P is the brother of M, M + N = M is the mother of N, N * Q = N is the sister of Q.

So, N and Q are two sisters. And M is the mother of two sisters. And P is the brother of M. So now we got P is the uncle of Q.

Nikhil S Beelur said: (Aug 3, 2016)  
Then why is option b is wrong?

Maithri said: (Aug 13, 2016)  
B) P + S x N - Q.

P + S -> P is the mother of S. It clearly implies P is a female. In the given question, P has to be the maternal uncle(-male), so we can conclude B is wrong option. :)

Rinku said: (Aug 19, 2016)  
If I say P - M + Q, is it right?

Because P - M means P is the brother of M and M + Q means M is the mother of Q.

So, p is the maternal uncle of Q.

Bhavani said: (Sep 20, 2016)  
Why it is not first option?

Krishna Reddy said: (Oct 9, 2016)  
@Anu you rocked, perfect explanation thank you so much.

Aniket said: (Oct 31, 2016)  
According to this relation, option 1 is also correct.

Anusha said: (Nov 17, 2016)  
Hi, I didn't get this problem. Please, someone help me with the clear explanation.

Ruchi Jain said: (Jan 6, 2017)  
Why first (A) option is incorrect?

Mrudula said: (Apr 1, 2017)  
The 1st option is also correct. It's same as the 3rd relationship.

Am I correct?

Deepshikha said: (May 25, 2017)  
Why option 1 is not correct?

Please explain me.

Pooja said: (May 30, 2017)  
I didn't understand it. Please explain it in clear.

Ramu said: (Jun 5, 2017)  
Not getting this, Please explain it clearly.

Siya said: (Jun 10, 2017)  
I too agree with option A.

Siyad said: (Jun 10, 2017)  
@Deepshikha @Mrudula @Ruchi Jain @Aniket @Bhavani @Siya.

First, read the question clearly. We have to show that P is maternal uncle of Q.
Let me show Explanation of option [A]:

Q - N ->' Q is the brother of N.
N + M -> N is the mother of M.
M x P -> M is the sister of P.

Therefore, Q is the maternal uncle of P.

So option [A] shows Q is the maternal uncle of P, this question is to show that P is maternal uncle of Q. So read the question carefully.

Hope you will understand :)

Vidhya said: (Jun 29, 2017)  
Why not A? Please explain me.

Rohit said: (Sep 14, 2017)  
Answere can be B.

Agrata said: (Oct 20, 2017)  
Right @Rohit.

Vrinda K said: (Oct 21, 2017)

Aarushi Yadav said: (Nov 4, 2017)  
I couldn't get this question.

Vandana said: (Nov 4, 2017)  
Why A option is not correct?

Hridya said: (Nov 4, 2017)  
Why not option number 1?

Narvinder said: (Feb 19, 2018)  
I didn't understand it please explain me.

Mukesh said: (Feb 22, 2018)  
P- M+NxQ

Now we have to find out the relation between p and q.

P-M means -ve sign denote brother of M.
M+N means +ve sign denote mother of N.
NxQ means x sign denote sister.

P is Maternal Uncle of q.

Aparna said: (Jun 1, 2018)  
Please explain the option A and C.

Shivangi said: (Jun 11, 2018)  
According to me, the answer is P - M + Q.

Paul said: (Jul 7, 2018)  
Mother's brother will be called paternal uncle not maternal uncle.

Patel said: (Jul 14, 2018)  


Shubhamkhedkar said: (Aug 26, 2018)  
Both A and C are right according to me.

Nil Sarkar said: (Mar 26, 2019)  
+mean mother, -mean brother, %mean father, *mean sister. As we know maternal uncle means brother of the mother. So, Q mother is M for (+). And his brother p for (-).
