A group of students surveyed a clothing store that sells only shoes, shirts, and ties for their upcoming MBA project. They surveyed for a week and noted down the numbers of customers who bought these products. Upon completing their survey the following observations were made:
1. The number of male customers who bought all 3 items and the number of female customers who bought all 3 are prime numbers, the difference of which is also an even prime number
2. Overall 40 of the customers bought only shoes which are also equal to the number of male customers who bought only shirts.
3. The total number of customers who bought only ties is equal to the number of female customers who bought only shirts.
4. 67 females bought shoes which is 1 less than the number of males who bought shoes.
5. Overall 29 females bought shoes and ties. Out of this, the number of females who bought only shoes and ties but no shirts is a non zero multiple of 5 which is also equal to the number of male employees who bought only ties.
6. Number of males who bought ties and shirts is 3 times the number of males who bought all 3 items
7. Number of males who bought ties is equal to the number of males who bought shoes.
8. 30 females only bought shirts which is double the number of females who bought only shoes.
