Question

Each contains a question of two statements I and II, giving certain data. Select the correct answer from $\left(1\right)$ to $\left(4\right)$ depending on the sufficiency of data given in the statements to answer each question.
$1$. If I alone is sufficient and II alone is not sufficient to answer the question.
$2$. If II alone is sufficient and I alone is not sufficient to answer the question.
$3$. If both I and II together are sufficient but neither statement alone is sufficient to answer the question.
$4$. If both I and II together are not sufficient to answer the question and additional data specific to the question are needed.
What is the ratio of the selling prices of two articles A and B?
I. The cost price of article A is equal to the selling price of B.
II. The profit made by selling A is equal to $1/5$ of its selling price.

• A. $1$
• B. $2$
• C. $3$
• D. $4$

Answer 1

The correct option is C $3$

C.P. of A = S.P. of B = $x$

S.P. of A = $y$

$y-x$ $=$ $\frac{y}{5}$

$\Rightarrow 5x=4y$

Ration of S.P of A and B =$5:4$

Both statement are required to answer the question.

Hence, Option C is correct.
