Twenty times a positive Integer is less than its square by 96. What is the integer?  Choose the most appropriate option
A) 4 B) 25 C) 24 D) 16 E) 27
Let the Integer be x.   Then X2 - 20X = 96   X2 - 20X - 96 = 0   X2 + 4X - 24X - 96 = 0 ===&gt; X(X + 4) -24(X + 4)   ===&gt; (X + 4)(X-24)   X = -4 or 24. as the Integer is positive the correct answer is   option 24)24
