In these questions, a question is given followed by information in three statements. You have to consider the information in all the three statements and decide the information in which of the Statement(s) is not necessarily required to answer the question and therefore can be dispensed with. Indicate your answer accordingly.
What is the labelled price of the article ?
I. Cost price of the article is Rs.500.
II. Selling price after offering 5% discount on the labelled price is Rs. 608.
III. Profit earned would have been 28% if no discount was offered.
Statement I : Only cost price is given, there is no information about labelled price or any other factor. Thus, it is insufficient.
Statement II : Let labelled price = $$100x$$
After 5 % discount, => $$100x - \frac{5}{100} \times 100x = 608$$
=> $$100x - 5x = 95x = 608$$
=> $$x = \frac{608}{95} = 6.4$$
$$\therefore$$ Labelled price = Rs. 640
Statement II is sufficient to find the labelled price
Thus, statement I & III are redundant.
