Easy one.... BUT important that we choose the BASE of % correctly...
increase of 1 on 8, so\(\frac{1}{8} * 100 = 12.5%\)
D

Opening = 8
Closing = 9

Rise in prise = 1

So, percent increase = \(\frac{1}{8}*100\) =>12.50%

Thus answer will be (D)

Increase in price = 9-8= $1
Original price= $8

% increase= 1/8*100= 12.5%

\(\frac{New-Old}{Old}\)=\(\frac{Closing-Opening}{Opening}\)

\(\frac{9-8}{8}\)=\(\frac{1}{8}\)=12.5%

Correct Answer (D) 12.5%
