Answer 1

The question is not complete, so i have attached the complete question.

Answer:

The two objects she can put are the paper back and the bar of soap.

Explanation:

From the attached image, we can see that the 3 weights are;

Paperback Book : 343 grams

Banana: 108 grams

Bar of soap: 117 grams

Now, she wants to find which 2 objects she can put on a pan balance to equal the weight of a 460 gram bag.

Now, to get this, 2 of the given objects when added together has to give 460 grams.

Let's add the weight of the paper book and Bar of soap. This gives;

343 + 117 = 460 grams

Adding any other combination of two of the given weights wouldn't give 460 grams.

Thus, the two objects she can put are the paper back and the bar of soap.
