Problem 12

Explanation

Let's check each statement based on the table data:

Regarding Pashmina vs Square Sales

The data shows $9 < 12$, $14 < 15$, $20 < 21$, and $27 < 30$. All are true, so this statement is Consistent.

Regarding Bergo vs Square Sales

In Week 1 ($14 > 12$) and Week 2 ($16 > 15$), Bergo sales are indeed higher. However, in Week 3 ($18 < 21$) and Week 4 ($20 < 30$), Bergo sales are lower. Thus, this statement is Inconsistent.

Regarding Bergo Sales Pattern

Bergo sales data is $14, 16, 18, 20$. The difference between weeks is always constant ($+2$), which means it forms an arithmetic progression. This statement is Consistent.

Regarding Weekly Sales Levels

If we look at all columns, every veil type experiences an increase in sales from week to week without any decrease. This statement is Consistent.

Regarding Bergo Sales Increase

Total increase for Square is $30 - 12 = 18$. Total increase for Pashmina is $27 - 9 = 18$. Meanwhile, total increase for Bergo is only $20 - 14 = 6$. It is true that Bergo has the smallest increase. This statement is Consistent.

In conclusion, the statement that is most inconsistent with the table is the claim that Bergo sales are always higher than Square sales.
