Answer : The oxidation state of nitrogen in $LiNO_3$ is, (+5)

Explanation :

Rules for the oxidation numbers :

The oxidation number of a free element is always be zero.
The oxidation number of a monatomic ion equal to the charge of the ion.
The oxidation number of Hydrogen (H) is +1.
The oxidation number of oxygen (O) in compounds is usually -2, but it is -1 in the peroxides.
The oxidation number of a Group 1 element in a compound is +1.
The oxidation number of a Group 2 element in a compound is +2.
The oxidation number of a Group 17 element in a binary compound is -1.
The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.

The given compound is, $LiNO_3$

Let the oxidation state of 'N' be, 'x'

$(+1)+x+3(-2)=0\\\\x=+5$
