Sir the way you taught Inference Rules is amazing. I don't mind the length of the videos because concepts should be covered in depth for GATE. And you it make it so easy to understand the concepts.

thank u sir i m very confuse about inference rule. but now it is clear

[sudeshnaC]

Thank you Sir.
Why can't we just simplify the inferences using the laws just as you did in the 1st example of inference rule? Logically thinking with Rani and Raju may be confusing at times.
