**Question

In a chocolate factory, the quality inspector noticed that in 1 hour, the number of chocolate boxes which had defective packing was 360 less than the number of boxes which were packed correctly.

If 60 more boxes were packed correctly in one hour, then the number of boxes that are packed correctly would be 25 times the number of boxes with defective packing.

What is the total number of chocolate boxes packed in 1 hour?

The correct answer is :

**520**
