is 1/a-b ‘<’ b-a?
(1) a ‘<’ b
(2) 1 ‘<’ |a-b|
(1) a ‘<’ b
(2) 1 ‘<’ |a-b|
From a )
a – b ‘<’ 0 i.e. a- b = -ve
b – a ‘>’ 0 i.e. b – a = + ve
Suff.
From b)
If a ‘>’ b ………a-b ‘>’ 1 & b – a ‘<’ -1
If a ‘<’ b ………a-b ‘>’ -1 & b – a ‘<’ 1
Depending on case we can have 2 possibilities’.
Hence Insuff.
Ans – A
