In an orchard there are apples, pears and oranges.
Pedro, Pablo and Juan take a piece of fruit each.
Pedro and Pablo take different fruits.
Pedro and Juan take the same fruit.
Neither Peter nor Paul catch pears.
If Pablo takes an apple, Juan also.
Could you say what fruit each one takes?
They tell us that "Pedro and Juan take the same fruit" and that "If Pablo takes an apple, Juan also". If Pablo took an apple, Juan would also take it and as they tell us that Pedro and Juan take the same fruit, the three would have an apple but since they also tell us that "Pedro and Pablo take different fruits" this could not happen. Thus, as we are told that "Neither Pedro nor Pablo pick up pears," Pablo must take an orange and Juan a different fruit that cannot be a pear since it must be the same fruit as Pedro's, which we know does not take a pear, then the fruit that Pedro and Juan take must be an apple.
In summary, Peter takes an apple, Pablo an orange and Juan an apple.
