If AD is median of △ABC and P is a point on AC such that ar(△ADP):ar(△ABD)=2:3, then ar(△PDC):ar(△ABC) is
AD is the median of △ABC, P is a a point on AC such that ar(△ADP):ar(△ABD)=2:3
Let area of △ADP=2x2
Then area of △ABD=3x2
But area of △ABD=12area△ABC
∴Area△ABC=2×area of △ABD=2×3x2=6x2
and area of △PDC=ar(△ADC)−ar(△ADP)=ar(△ABD)−ar(△ADP)=3x2−2x2=x2∴Ratio=x2:6x2=1:6
