1.	The length of rectangular field is increased by 50% and it's breadth is decreased by 50% to form a new rectangle. Then the percentage change in the area of the field is:
Answer» LET the ORIGINAL length=p and breadth=qoriginal area= pqnew length= p+p/2=3p/2 andnew breadth= q-q/2= q/2new area=(3p/2)×(q/2)=3pq/4chanse in area = PQ -(3pq/4) =pq /4% CHANGE = (pq /4)×100/(pq) = 25%
