Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

here is the explanation. each side of star is also scaled by k. see the expression of "R12", In its expression, if you multiply each resistance in RHS by "k", then k^2 will come out from Numerator, and k can be taken out from denominator. so overall only k remains. Best regards.

dear you can ignor that. they have taken a case to show you. they have written. "if" in front of that statement. they are solving by taking any values to minimise the calculation.
