Conclusion 1: All purses are pink → True (This is definitely true)
[ alt="F2 S.Y 25.2.20 Pallavi D2" src="//storage.googleapis.com/tb-img/production/20/02/F2_S.Y_25.2.20_Pallavi_D2.png" style="width: 111px; height: 61px;">
Conclusion 2: All pink are coins → False (Possible but not definite)
Conclusion 3: All rupees are purses → False (Possible but not definite)
Conclusion 4: All coins are pink → True (This is definitely true)
