CAT/1997
Question . 87
What is the cost price of the chair?
I. The chair and the table are sold, respectively, at profits of 15% and 20%
II. If the cost price of the chair is increased by 10% and that of the table is increased by 20%, the profit reduces by Rs. 20
Explanatory Answer
Method of solving this CAT DILR Question from Data Sufficiency question
(d) Let the cost prices of the chair and the table be Rs X and Rs Y respectively from.
Therefore, corresponding selling prices are Rs. 1.15X Rs. 1.2Y and profit is Rs (0.15X + 0.2Y)
From II the profit is Rs. 0.05 X
hence 0.05x = 0.15x + 0.2y 20
Which can’t be solved. Therefore, even both statements together are not sufficient to answer the question.
