The answer is clearly D. I am a sophomore in high school and I can figure it out. Company A’s net stock increase is 56%, while Company B’s is 53%. 53 - 56 = -3, which is
less than -1. (continuation of above post)
The answer is (D)
Yup. There it is. Each increment builds on the hypothetical starting price. m(1.3)(1.2)=1.56 or 56% and so forth.
Answer D:
Lets take a number to calculate numbers:100
m = 156
n 153
n-m
