Direction: Study the table below and answer the following questions. There are five sellers P, Q, R, S and T. They are selling four different items. The discount (as percentage) is given on the marked price of these four items by different sellers. |
(Note: 1. Some values are missing. You have to calculate these values as per data given in the questions.) |
2. Marked price of a particular item is same for all of the sellers. |
A) 2
B) 3
C) 7
D) 5
E) None of these
Correct Answer: D
Solution :
Let the MP of item II of seller P be x and that of item II of seller R be x. Then, the cost price of item II of seller P \[=\left( \frac{100}{100+m} \right)\times \frac{70x}{100}\] Cost price of item II of seller R \[=\left( \frac{100}{100+2m-5} \right)\times \frac{85x}{100}\] According to the question. \[\frac{\left( \frac{100}{100+m} \right)\times \frac{70x}{100}}{\left( \frac{100}{100+2m-5} \right)\times \frac{85x}{100}}=\frac{14}{17}\] or, \[\frac{100+2m-5}{100+m}\times \frac{70}{85}=\frac{14}{17}\] or, \[100+2m-5=100+m\] \[\therefore \]\[m=5\]You need to login to perform this action.
