If A + B means A is the brother of B; A - B means A is the sister of B and A x B means A is the father of B. Which of the following means that C is the son of M?

 [A]. M - N x C + F [B]. F - C + N x M [C]. N + M - F x C [D]. M x N - C + F

Explanation:

M x N → M is the father of N

N - C → N is the sister of C

and C + F → C is the brother of F.

Hence, M is the father of C or C is the son of M.

The trick to solve the question is as follows: Step 1: make out the conditions from the question, for example in this question it says ''c is the son of M''. here we can configure the conditions as follows- Condition 1- c must be a male in the equation. COndition 2- M should be father or mother in the equation. Based on these conditions we can filter the options and the remaining conditions can be checked finaaly to confirm the answer. for example in this question : 1st option: c+f means c is brother of F. it confirms that c is a male. and M-N means M is sister of N, here M is neither a father nor mother, so this condition we can take it as a wrong and can avoid it. 2nd Option: C+N means C is brother of N, it confirms that C is a Male. N*M, here M has came in last, so we can not determine the sex of M. So this Option also we can filter out. 3rd Option: F*C means C came in last of the equation and we can not determine the sex of the C. this also we can filter it out. the remaining option is four. so we can check the fourth option to check it is correct. Basically on the basis of the question we have to make the conditions and on the basis of these condition we have to filter out the options. Do practice of it, and you will find very easy to solve these types of questions.

Try to make a rough diagram in these sorts of sum it easiens the question and allows you to answer in better way. Hope it helps you.

 Vinay said: (Mon, Sep 17, 2012 01:00:03 PM) @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.
