If each side of a square is increased by 50%, the ratio of the area of the resulting square to the area of the given square is: Pick one: A) 5:4 B) 9:4 C) 4:5 D) 4:9 E) 1:2
Let, each side=a. Then, original area= a2.   New side= 150a/100= 3a/2. New area= 9a2/4.   Required ratio= 9a2/4:a2= 9:4   ANSWER:9:4
