Four Fruits ...!!


In a contest, four fruits (an apple, a banana, an orange, and a pear) have been placed in four closed boxes (one fruit per box). People may guess which fruit is in which box. 123 people participate in the contest. When the boxes are opened, it turns out that 43 people have guessed none of the fruits correctly, 39 people have guessed one fruit correctly, and 31 people have guessed two fruits correctly.

How many people have guessed three fruits correctly, and how many people have guessed four fruits correctly?

There cannot be people who can guess only one answer wrong as everyone are aware of the name of the 4 fruits and they cannot guess a name outside the four. So if they guess one wrong then there should be another box wrongly guessed as well.
