Verbal Reasoning - Blood Relation Test - Discussion

The correct one is M x N - C + F.

Read it from left to right.

M x N → M is the father of N
(M is the dad of N)

N - C → N is the sister of C (N is sis of C, so C must be a boy)

C + F → C is the brother of F(confirms again, C is a boy)

Let’s pull it all together;
M x N → M is dad of N.

N - C → N is the sister of C → So C is also a child of M, since N and C are siblings, and M is the dad.

C + F → C is the brother of F → confirms C is male.

So C is the son of M.

Final Breakdown:
Person -- Relation
M -- Father
N -- Daughter
C -- Son (our target 🎯)
F -- C's sibling (no gender needed)

So, the Final answer:
M x N - C + F.
C is the son of M!

Option 1 M - N * C + F is also correct right?

Please explain the answer in detail.

Option B is also correct as F is sister of C and C is brother of N and as M is father of N, M should be father of all F, C and N.

M may be father or mother of c. So why not the option 2 is correct?

Thanks @Vikas Saini.

How C comes last of the equation? Could you please Give give me a clarity?

Can somebody explain essay steps to identify the blood relation ?

@Sanjay Bisht.

As the A B are actually in order
So I think the letters whch are given in options also should be taken in order. Which means F*c is given whch is wrong in alphabitical order. and same for N*M also
if it was like (C*F)as(A*B)then c would have also considered as father of F....but it is given as F*C which is wrong in alphabetical order. So it ruled out.

Nice explanation @Vikas.
