How to solve assertion reason questions

Solve assertion-reason type questions

Assertion reason type questions come in almost all exams. So assertion reason questions are important for success for getting good ranks

Assertion reason type question has these five different cases
1. Both assertion and reason are true, reason is the correct explanation of assertion.
2. Both assertion and reason are true but the reason is not a correct explanation of the assertion.
3. Assertion is true but the reason is false.
4. Assertion is false but the reason is true.
5. Both are false.

Assertion reason type of questions tests only the concepts of the students. A reasonably well-prepared student can answer assertion reason-type questions in a matter of a few seconds.

Here are the steps to move forward

(a) First you need to read both the sentences to see if they are correct or incorrect. If you are able to find an incorrect statement, then you have automatically cracked the problem and This case falls under the last three options. Now if option 5 is not present in your case, then just seeing one incorrect statement solves your question. Now if option 5 is present, you need to look at the correctness of the other statement also

(b) Now if you find that both the statements are correct, then options 1 and 2 come under the picture. It is the most confusing part for most of the students.The easier ways to solve in that case to write like this  <assertion statement >  is true because < reason statement>.  If that makes sense to you based on the concept then option 1 is correct else option 2

Definitely, concept clarity is very important for solving these types of questions.
In the case of Maths, you can use randomly substitute the values to find the correctness of the mathematical equations

Here are some Examples for  assertion reason questions
The following questions consist of two statements, Assertion and Reason. While answering these questions choose any of the following four responses
A. If both assertion and reason are true and the reason is the correct explanation of assertion.
B. If both assertion and reason are true but the reason is not a correct explanation of assertion.
C. If the assertion is true and the reason is false.
D. If both assertion and reason are false.

1. Assertion: In a series LCR circuit, resonance occurs only at one frequency.
Reason:  At this frequency, inductive reactance is equal to capacitive reactance.
(a) A
(b) B
(c) C
(d) D

2. Assertion: Insulators do not allow the flow of current through themselves.
Reason: They have no free-charge carriers.

(a) A
(b) B
(c) C
(d) D
3. Assertion: When the temperature of the cold junction of a thermocouple is lowered, the value of the neutral temperature of this thermocouple is raised
When the difference of temperature of two junctions is raised, more thermo e.m.f. is produced.

(a) A
(b) B
(c) C
(d) D
4. Assertion: If two parallel wires, hanging freely are connected to a battery in series, they come closer to each other.
Reason: Force of attraction acts between two wires crying charge

(a) A
(b) B
(c) C
(d) D
5. Assertion: If an electron and proton enter an electric field with equal energy, then the path of the proton is more curved than that of the electron.
Reason: electrons have a tendency to form curves.
(a) A
(b) B
(c) C
(d) D

6)Assertion: When lightning strikes, the sound is heard a little after the flash is seen.
Reason: The velocity of light is greater than that of sound.


1. a
2. a
3. d  here both assertion and reason are not true
4. d when two long parallel wires are connected to battery in series they carry current in opposite direction and hence repel each other.
5. d
6 a
