The question carries an error! There are five nails and half of 5 is 2.5. It is now a meaningless assertion to say 2.5 nails (question says half of the nails and half of the nuts are rusted) are rusted. Kindly rectify the mistake and forward it once again.

Half of 5 nails??

I think, half of the nails = 5/2 which is not appropriate, because counting nails cannot be a fraction
