Answer: B and F
Step-by-step explanation:
Since, In the first case original amount = 45
So, the increasing percentage when the original amount increases to 75,
= [tex]\frac{75-45}{45} \times 100 = \frac{30}{45} \times 100= \frac{200}{3}[/tex] %
In second case original amount = 75
So the decreasing percentage when the original amount decreases to 45,
= [tex]\frac{75-45}{75} \times 100 = \frac{30}{75} \times 100= \frac{40}{1}[/tex] %
Thus, We found that the ratio of the percent increase is not the same as the percent decrease ( because, [tex]\frac{200}{3}\neq \frac{40}{1}[/tex]
Also, The original amount of the present increase is different from the original amount for the persons decrease. ( Because, [tex]75\neq 45[/tex]
Therefore, Option B and F is correct only.
