Aptitude - Profit and Loss - Discussion
Each of the questions given below consists of a question followed by three statements. You have to study the question and the statements and decide which of the statement(s) is/are necessary to answer the question.
What was the percentage of discount given? | |
I. | 23.5% profit was earned by selling an almirah for Rs. 12,350. |
II. | If there were no discount, the earned profit would have been 30%. |
III. | The cost price of the almirah was Rs. 10,000. |
I. S.P. = Rs. 12350, Gain = 23.5%
 C.P. = Rs. |
 |
100 | x 12350 |  |
= Rs. 10,000. |
| 123.5 |
II. M.P. = 130% of C.P. = 130% of Rs. 10,000 = Rs. 13,000.
From I and II, discount = Rs. (13000 - 12350) = Rs. 650.
| Discount % = | |
650 | x 100 | % = 5%. |
|
| 13000 |
Thus, I and II give the answer.
II and III can not give the answer. Because we require profit percentage with discount and profit percentage without discount. So II and III are not sufficient.
Since III gives C.P. = Rs. 10,000, I and III give the answer.
Therefore, I and II [or] I and III give the answer.
Correct answer is (E).
We have to find the discount per cent so we require printing or M.P of the item such that we can calculate the value with the help of 2nd option. Thus Only I and II are necessary to answer.
Option A should be correct.
Here Options I and III are the same as they both provide the Cost price only.
So, the correct answer should be A.
Also, we can get CP from either I or III.
[Note: It's not necessary to verify whether the CP is got by confirming the application of discount% as CP is fixed as we are talking about the same commodity].
