Answer:

The correct option is B) 2.

Explanation:

Consider the provided information.

Blue, green, purple and red chips worth 1, 5, x and 11 points each, respectively.

The worth of purple chips is 5<x<11

The product of the point values of the selected chips is 88,000.

Calculate the prime factorization of 88,000.

88,000 = 2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × 5 × 11

or 88,000 = 2⁶ × 5³ × 11

It means we have selected 3 chips of green and 1 chips of red. But there is no chip whose worth is 2. Also we know the value of x must be between 5 and 11.

2⁶ = 2³ × 2³ = 8 × 8

Hence, the value of purple chip is 8 and 2 purple chips is selected.

Therefore, the correct option is B) 2.
