Each question is followed by two statements, I and II. Mark the answer:

1. If the question can be answered by using one of the statements alone, but cannot be answered using the other statement alone.

2. If the question can be answered by using either statement alone.

3. If the question can be answered by using both statements together, but cannot be answered using either statement alone.

4. If the question cannot be answered even by using both statements together.

What is the selling price of the mixture, if the ratio of the two qualities of rice mixed is 3:5?

I. Cost price of the first quality of rice is Rs. 20/kg.

II.Cost price of the second quality of rice is Rs. 28.5/kg.

Let’s break it down:

- The question is about finding the selling price of a rice mixture, with a given mixing ratio (3:5 for two types).

- Statement I: Gives only the cost of first quality rice (Rs. 20/kg).

- Statement II: Gives only the cost of second quality rice (Rs. 28.5/kg).

What this really means is:

- Even if you use both statements, all you know is the cost prices for each kind of rice and the mix ratio.

- The selling price? Not mentioned, not even hinted. You don’t know the profit margin, overhead, or if they're selling at a loss.

- So, neither statement alone, nor both together, are enough to answer the actual question.

Let’s match to your provided options:

Option 4 says: "If the question cannot be answered even by using both statements together."

That’s exactly this situation.

Correct Answer: Option:4, 4

To sum up, all you get is costs and the ratio. Without the selling price details, you’re out of luck.
