What is the percentage profit on the cost price? (M.A.T., 2008) I. The cost price is ` 368.35. II. There is a 20% profit on the selling price.
Answer
SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
II. Let S.P. $=₹x$. Then, profit $=20\%$ of ₹$x=₹\frac{x}{5}$. $$\text{C.P.}=₹\left(x-\frac{x}{5}\right)=₹\frac{4x}{5}. \therefore \text{Profit \%}=\left(\frac{x}{5}\times\frac{5}{4x}\times 100\right)\%=25\%.$$ So, II alone gives the answer, while I alone does not. ∴ Correct answer is (b).
