Discussion Forum : Profit and Loss - Data Sufficiency 4 (Q.No. 1)
Directions to Solve
Each of these questions is followed by three statements. You have to study the question and all the three statements given to decide whether any information provided in the statement(s) is redundant and can be dispensed with while answering the given question.
1.
What is the percent profit earned by the shopkeeper on selling the articles in his shop? | |
I. | Labeled price of the articles sold was 130% of the cost price. |
II. | Cost price of each article was Rs. 550. |
III. | A discount of 10% on labeled price was offered. |
Answer: Option
Explanation:
I. Let C.P. be Rs. x.
| Then, M.P. = 130% of x = Rs. |  |
13x |  . |
| 10 |
III. S.P. = 90% of M.P.
| Thus, I and III give, S.P. = Rs. | |
90 | x | 13x | |
= Rs. | |
117x | |
| 100 | 10 | 100 |
| Gain = Rs. | |
117x | - x | |
= Rs. | 17x |
| 100 | 100 |
Thus, from I and III, gain % can be obtained.
Clearly, II is redundant.

Shouldn't it be B? Please explain.

From the (i) we can make CP = 100 and MP = 130.
From the (iii) we can make SP = 117.
And now we can calculate profit %.
(17/100) * 100 = 17% profit.
From the (iii) we can make SP = 117.
And now we can calculate profit %.
(17/100) * 100 = 17% profit.

If s.p = 130% of c.p then s.p = 1.3c.p
(s.p-c.p)/c.p * 100.
(1.3cp - c.p) /c.p *100.
Let cancelled c.p
0.3*100
30% profit gain I thing option I only.
(s.p-c.p)/c.p * 100.
(1.3cp - c.p) /c.p *100.
Let cancelled c.p
0.3*100
30% profit gain I thing option I only.

If s.p = 130% of c.p then s.p = 1.3c.p.
(s.p-c.p)/c.p * 100.
(1.3cp - c.p) /c.p *100.
Let's cancel c.p.
0.3 * 100.
30% profit gain. So, I think option I only.
(s.p-c.p)/c.p * 100.
(1.3cp - c.p) /c.p *100.
Let's cancel c.p.
0.3 * 100.
30% profit gain. So, I think option I only.

Isn't the answer should be B, because statement 2 is redundant and we have to find redundant statements right?

No @Showry.
The p% is 107%.
(588.5*100)/550 = 107%.
The p% is 107%.
(588.5*100)/550 = 107%.

No, Option 2 is correct because it's been asked redundant one.

But in question what asked is that which option is redundent so option 2 should be correct.

Assume cp is x.
so Mp is 1.3x.
and the discount is 10 of mp.
So sp is 1.17 x.
Make linear equation cp always can side 100%
x=100%.
1.17x=Y%.
by the cross multiplication get Y%.
profit is (Y-100)%.
No need to consider no of articles because they cancel each other.
So the answer is 1 and 3.
so Mp is 1.3x.
and the discount is 10 of mp.
So sp is 1.17 x.
Make linear equation cp always can side 100%
x=100%.
1.17x=Y%.
by the cross multiplication get Y%.
profit is (Y-100)%.
No need to consider no of articles because they cancel each other.
So the answer is 1 and 3.

Since it is asked which is redundant, so the answer should be "B) Only II". Since other two are required to answer.
