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.

All the three are required to answer the question. Moreover, the answer must be definitive enough and since the II statement gives the C.P, that datum is required.

hey guys what i think is........All the three are required
1)L.P=130% of C.P ==> L.P=[(100+130)/100]* c.p
2)c.p=550.rs L.p= (230/100)*550.....L.P=1265.rs
3)10% discount on L.P..... So,
lets take L.p as C.P to find loss
10=(loss*100)/1265....
and loss=126.5 rs
Now Article actually sold at S.P= L.P-loss
S.P =1265-126.50
S.P= 1138.50 rs
But Profit %?????????????????
C.P=550 & S.P=1138.50 Profit= 588.50
P % = (588.50*100)/550
P%=17%
