An artist has exactly seven paintings --- ,T,U,V,W,X,Y, and Z -- from which she must choose exactly five to be in an exhibit. Any combination is acceptable provided it meets the following conditions:

* If T is chosen , X cannot be chosen
* If U is chosen , Y must also be chosen
* If V is chosen , X must also be chosen

• T, U, W, Y, Z..
  
  if we take v, then we should choose x also.. hence by leaving v and x and selecting the remaining..
  
  if we take v, then x is also taken so t should not be taken, in this case z is not choosen.. which is not correct. soo, taking v and x, thereby leaving y. :-)
