Say y=1 and x=8.

Then y=1 is less than x=8 by (8-1)/8*100=7/8*100=87.5%.

Answer: B.

Answer = B

For \(y = \frac{1}{8}, x = 1\)

\((1 - \frac{1}{8}) * 100 = \frac{7}{8} * 100 = 87.5%\)

x=8
y=1

the percentage y of x is 1/8*100=100/8

the difference in percentage is 100-100/8=700/8=87.5

B

intuitively C is too simple, other unrealistic, so B fits
