What to Study in Blood Relation for RRB ALP?
In the RRB ALP exam, Blood Relation simply means finding the family connection between two people based on the clues given in the question. You do not need to read thick books for this. You just need to learn how to draw a family tree on your rough sheet. Below are the only 3 rules you need to know:
- Generations go Up and Down: Your grandparents are at the top, your parents are below them, you and your brothers or sisters are in the middle, and your children are at the bottom.
- Gender Signs: Always use a “Plus (+)” sign or a “Box” for males (boys/men). Use a “Minus (-)” sign or a “Circle” for females (girls/women).
- Marriage and Siblings: Use a double line (=) between a husband and wife. Use a single line (-) between brothers and sisters.
The 3 Main Parts of Blood Relation in RRB ALP:
- Pointing or Indicating Form: Where someone points to a photo and tells a relation.
- Family Tree or Puzzle Form: Where direct relations like “A is the brother of B” are given.
- Coded Form: Where symbols like +, -, *, % are used to show family connections.

5 Simple Tips to Prepare Blood Relations for RRB ALP
You do not need to be a genius to solve these questions. Just keep a cool head and follow these 5 easy tips:
- Never Guess Gender by Name: Just because a name is “Rohan” or “Kiran”, do not assume they are a boy or a girl. Always look for words like “brother,” “sister,” “his,” or “her” to confirm.
- Always Draw the Family Tree: Never try to solve family puzzles in your head. Always draw the tree on your rough sheet. Put older generations on top and use plus (+) for males and minus (-) for females.
- Break Down Pointing Questions: For questions starting with “Pointing to a man…”, break the sentence at the word “my”. Solve the speaker’s side first, and then connect it to the person they are pointing at.
- Use the “Self” Trick: Sometimes, the easiest way to solve a pointing question is to put yourself in that situation. Imagine your own uncle or aunt. It helps you find the answer faster!
- Practice Previous Year Papers: Railway exams repeat the pattern of Reasoning questions every year. Solve the previous year’s blood relation questions of RRB Group D, NTPC, and ALP. You will see that they are very easy.

FAQs: Blood Relation Questions for RRB ALP Exam
No, not at all! The reasoning section in CBT 1 is very basic. The blood relation questions can be solved easily if you draw a simple family tree diagram on your rough sheet.
Out of the 25 questions in the Reasoning section, you can comfortably expect 1 to 2 direct questions from Blood Relations.
Absolutely not! Blood relations is a purely logical topic. There are no math formulas here. You just need to know basic family connections like uncle, aunt, niece, and nephew.
If the question says “A is the child of B,” you cannot assume A is a boy or a girl. In such cases, if the options ask for the exact relation, look for options like “Son or Daughter” or “Cannot be determined.”
Yes, simple coded relations (like A+B means A is father) are sometimes asked. But they are very short and direct, not long and confusing like banking exams.
