Directions to Solve

Each of the questions given below consists of a statement and / or a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statement(s) is / are sufficient to answer the given question. Read the both statements and

  • Give answer (A) if the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.
  • Give answer (B) if the data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.
  • Give answer (C) if the data either in Statement I or in Statement II alone are sufficient to answer the question.
  • Give answer (D) if the data even in both Statements I and II together are not sufficient to answer the question.
  • Give answer(E) if the data in both Statements I and II together are necessary to answer the question.

1.

A man mixes two types of rice (X and Y) and sells the mixture at the rate of Rs. 17 per kg. Find his profit percentage.

I. 

The rate of X is Rs. 20 per kg.

 II. 

The rate of Y is Rs. 13 per kg.

I alone sufficient while II alone not sufficient to answer
II alone sufficient while I alone not sufficient to answer
Either I or II alone sufficient to answer
Both I and II are not sufficient to answer
Both I and II are necessary to answer
Answer: Option
Explanation:

The ratio, in which X and Y are mixed, is not given.

So, both I and II together cannot give the answer.

Correct answer is (D).

x 20/-
Y 13/-

Cp = 20+13 = 33.
Sp = 17x2 = 34.

Profit = (1/33)x100.
Option E.
(1)

Here the quantity of rice x and y are not given so data is insufficient.

Ratio of mixture = 4:3.

Let us consider he mixes 4 kg of type one mix and 3 kg of type 2.

His cost price = (4*20) + (3*13) = 119.

Selling price = 7*17 = 119.

No profit no loss.

Vibha said:   10 years ago
Option D is correct.

We can calculate the ratio in which both X and Y are mixed using mixtures n alligation but to calculate profit we need the total quantity of mixture, which is not given.

"General Thinking" answer D is correct. Because the quantity is not mentioned. Suppose the shopkeeper mixes only some amount of X on Y or else only some amount of Y on X. It depends on the shopkeeper.

Average of (x+y) = 17/kg (for sell).

But x = 20/kg.

y = 13/kg.

Here, average of (x+y) = (20+13)/2 = 16.5/kg (cost price).

Profit percentage = (17-16.5)/16.5*100 = 3%.

We have to calculate profit per.

So it requires cost price ===> given but not clear that in what ratio we mixed them. So we have not cost price, and selling price is 17/kg but cost price is not clarify. So and D is correct.

We need both A and B to find profit. So option E is right.

Sparsh Chandra said:   1 decade ago
Option E will be correct only if both the type of rice are mixed in same ratio. So answer 100/33% = 3.33% as solved by AMIT is correct but here it is not defined whether the mixture of them was done in same ratio or different.

So D will be correct. So the question is not exactly defined.

Harshad said:   1 decade ago
No option E is incorrect. Right answer is D.

Because the ratio of mixing is important. We just can't assume he mixed same quantity of both rice (x and y).

What if he mixed 1 kg of x and 9999 kg of y.
So total 10,000 kg and cost will be (20+9999*13) = 1,30,007.

And sp for 10000 kg =17*10000 = 1,70,000.

Profit = 39993 and % will be 3.07.

And what if we consider the other way round. Like what if he mixed 1 kg of y and 9999 kg of x.

That time he will be in loss.
