Simple and easy solution

 It was a famous soap production factory.

The soap manufactured in the factory is very famous for its quality.

Once the packet in which soap cake is kept, was empty   !!!!

In all other packs, soap cake was kept but only in one pack, soap cake was missing !!!

This perticular soap pack is bought by a person who was shocked by seeing the empty packet. 

Soon the news became viral on both social media and newspapers.

Sales of that perticular soap got hit and factory started to face losses. 

Owner of the soap factory was worried and consulted experts to rectify the issue in coming days. 

Experts suggested to keep a  laser sensor  before dispatching the soap to make sure they really contain soap cake inside the packet.

Likewise owner arranged for those costly laser sensors.

He called a press meet to describe what are the precautions they have taken before dispatching for market. 

A reporter suggested a simple and easy solution for the problem. 

Instead of keeping those costly laser sensors, owner could have kept a turning fan  !!!!

If the packet is empty, it will just get blown away leaving behind the correct filled packets  !!!!
