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,

=  \frac{75-45}{45} \times 100 = \frac{30}{45} \times 100= \frac{200}{3} %

In second case original amount = 75

So the decreasing percentage when the original amount decreases to 45,

=    \frac{75-45}{75} \times 100 = \frac{30}{75} \times 100= \frac{40}{1} %

Thus, We found that the ratio of the percent increase is not the same as the percent decrease ( because,   \frac{200}{3}\neq \frac{40}{1}

Also, The original amount of the present increase is different from the original amount for the persons decrease. ( Because, 75\neq 45

Therefore, Option B and F is correct only.
