Answer
SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
I. $\mathrm{F}+\mathrm{S}=50$ II. $3(\mathrm{F}+\mathrm{S})=5\mathrm{F}$ From II, we get $2\mathrm{F}=3\mathrm{S} \Leftrightarrow \frac{\mathrm{F}}{\mathrm{S}}=\frac{3}{2}$. Thus, II alone gives the answer, but I alone does not give the answer. Correct answer is (b).
