The correct option is C 104.5 crore
Since, the line AB passes through points A(1985,92) and B(1995,97), its slope is
97−921995−1985=510=12
Let y be the population in the year 2010
So, the line AB passes through C(2010,y),
∴ Slope of AB= Slope of BC
⇒12=y−972010−1995⇒12=y−9715⇒152=y−97⇒y−97=7.5⇒y=7.5+97=104.5
Thus, the population in 2010 is 104.5 crores.
