Family Tree Method to solve Blood Relations Questions

Note – This method is copyright of PrepInsta, you will only find it on PrepInsta, using this method to solve will lead to copyright issue.

Rules –

  • Use + or Male and (-) for female
  • Imagine your family in the situation if you get stuck
  • Keep same generations at same level
  • Circles mean they are couple, i.e. husband and wife.
  • Array means you’re going down to next generation. i.e. A -> B means a is father or mother of B.
    • (+)A-> B means a is father of B.
    • (-)A-> B means a is mother of B.
  • If you miss a generation due to no information provided then name them ? for time being
    • A is grandfather of C, will be (+)A -> ? -> C
  • You also make circles and two ? if you think that later on couple relationship may be established
    • A is grandfather of C, will be (+)A -> (**inside Circle?/?inside Circle**) -> C (see example 1 for demo)
  • Always give Initials for names i.e. R for Raman, Aj for Ajay and Ak for Akash.
  • If there is no tight relationship(Mostly in case of in Law type questions which are complicated) use dotted arrays and to multiple relationships possible.

Let us learn from an example – 

Ques. A is sister of B. C is the father of B. D is the wife of C and E is the father of D. How is E related to B?

Ans. Now, basic approach that you may be following is let us assume I am B so A is my siter….. you will start like this. Now, this approach may work well in easy questions, but not work in following instances

  • Doesn’t work with long, lengthy and difficulty questions. Since, mind can’t store a 3 level of great great grandfather and in laws type of relationships info (We did a survey average mind can only remember/apply logic to upto 6 relationships not more.
  • Second case you will either assume yourself as male or female automatically, while in the question the person you applying your position logic to, may be of different gender than yours, so you will come at wrong outcome

In these cases Family Tree method works –

Now let’s look at the problem again.

Ques. A is sister of B. C is the father of B. D is the wife of C and E is the father of D. How is E related to B?

A is the sister of B consider this situation and lets come at outcomes

  • A is female
  • A is sister of B
  • B’s sex is unknown
  • A and B’s parents are unknown

All this info can be drawn in 5 seconds like we have done in the right hand side

C is the Father of B from this we get to know the following after adding to Family Tree

  • C is male
  • C is father of B
  • C is also father of A
  • Mother is still known
