Since the the biography collection of the library amounts to 37.5%
I thought of assuming the actual number to be 75.
and thus the total number of new books would come to 200
Thus the number of books before the purchase would be 200-75 = 125 (Since only the biographies were added)
thus 20% of 125 = 25
therefore the % increase in biographies would be (75-25)/25 = 200% (which is no where in the answer choices....
Can someone plz tell me where am I going wrong.......?????
