Problem

If M is 30 \% of Q, Q is 20 \% of P, and N is 50 \% of P, then \frac {M}{N} =


\mathrm{(A) \ \frac {3}{250} } \qquad \mathrm{(B) \ \frac {3}{25} } \qquad \mathrm{(C) \ 1 } \qquad \mathrm{(D) \ \frac {6}{5...

Solution

We are given: M=\frac{3Q}{10}, Q=\frac{P}{5}, N=\frac{P}{2}. We want M in terms of N, so we substitute N into everything:

\frac{2}{5}N=\frac{P}{5}=Q

M=\frac{3N}{25}

\frac{M}{N}=\frac{3}{25} \Rightarrow \mathrm{(B)}
