P+F=C+2 P=PHASE F=DEGREE FREEDOM C=components 2 represents pressure, temperature 5 phase must be present for this 3componet system having degree of freedom zero./invariant. P+F=0 = 3+2 for F to be zero 5 phase must be there. question has mistakenly written 5 phase.
![eduncle-logo-app]()
why u wrote mistakenly written 5phase..?u meant the question should ask degrees of freedom
![eduncle-logo-app]()
no should ask how many phases present at invariant point.

Answer = 5, The question is itself mentioning the answer. They have mistakenly written the number of phases=5, which is the answer in actual. As you know that, F=C-P+2, for invariant point F=0, C=3 given in the question. So, P= C-F+2 = 5.
thank u so much sir.i got it
