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 profit percentage made by the shopkeeper?

I. Selling price of 100 eggs is Rs. 120.

II. Cost price is two-thirds of the selling price.

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

Solution

This gives us only the selling price (SP = Rs. 120 for 100 eggs).

But no cost price (CP) is given, so we cannot calculate the profit or profit percentage.

**Statement I alone is not sufficient.

This gives us a relationship between CP and SP, i.e.:

CP = 2/3SP

Profit percentage = (SP- CP) / CP x100

So, even without the actual SP value, we get a definite profit percentage.

Statement II alone is sufficient.

So, even without the actual SP value, we get a definite profit percentage.

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