We all must have seen carpenters working with wood and also using nails to fit things together. Here is a situation, where a carpenter is working at a school, and there is a fun and tricky question to be answered in the end.

Situation:

An ex-student, who had now become a successful businessman, donated a new nameplate to the school. The school’s name was artistically engraved on a shining metal plate, which was square in shape. A carpenter fixed the plate on a wooden plank before putting it up on the main entrance. Satish noticed that the carpenter had put 25 nails on each side of the plate and each nail was put at the same distance apart.

What do you need to answer?

How many total nails were used by the carpenter?

Answer:

The carpenter used 96 nails.

Explanation:

The four corners each would have one nail. So, four corners have four nails and in addition to that, there are 23 nails on each side. Hence, the total number of nails that the carpenter used would be 23×4+4 = 96.
