I have no idea what you mean by, "We take the sum of voltage 60 + I(pi) at point 1." Is that supposed to be an answer to one of the three questions I asked? If so, which one?We take the sum of voltage 60 + I(pi) at point 1.
then why we not taking the sum of voltage 60 + I(pi) at point 2 because the the two source also connected to this point.
