can anyone explain me this enequality... P=>Q>R=>S=T In this how Q>T is true and P=>S is false .means how this can be determined that ...

easy. If in a chain of >= if any other sign will come then it will be false eg. a>=b>=c>d then a>=d will be false but for a>=c will be true. bcoz >= means that the conclusion can be 50%> & 50% = but if someone ask me that will the ans. be 100% > or = then the ans will be false.

Okk , but here is R>=S in btw Q>T nd T=S So new statement is P>=Q>R>=S or T So here also 50% > and 50% = ,then how this will be true

Plzz dont ignore this m too confuse in this type of inequality....
