A third of the company stayed in the camp, while the rest went to the shooting range. Those who stayed in the camp ate a quarter of the prepared soup for lunch, and those who returned from the shooting range in the evening received portions one and a half times larger than those given for lunch. How much soup was left for the company's dog, Naida?
$2 / 3$ of the company went to shooting, which is twice as many as those who remained in the camp. If they had received the same portions as were given at lunch, they would have eaten twice as much as was eaten at lunch, that is, half of the prepared soup. Since in reality their portions were one and a half times larger, they ate $3 / 4$ of all the soup. And since $1 / 4$ of the soup had already been eaten at lunch, nothing was left.

## Answer

Nothing was left.
