P percent of 160 = \(\frac{P}{100}\)*160
Q percent of 40 = \(\frac{Q}{100}\)*40

\(\frac{P}{100}\)*160 = \(\frac{Q}{100}\)*40.

Solving gives 4P = Q.

Therefore \(\frac{P}{Q}\) = \(\frac{1}{4}\)

B is the answer.

A. Cannot be determined
B. 1/4
C. 2/5
D. 5/2
E. 4


\(\frac{p}{100}*160 = \frac{q}{100}*40\)

Or, \(4p = q\)

So, \(\frac{p}{q} = \frac{1}{4}\), Answer must be (B)

1.6p=0.4q

\(\frac{p}{q}\)= \(\frac{0.4}{1.6}\)= \(\frac{1}{4}\)

Answer: B.
