Answer:
The firm will not sell any bundle, the amount of bundle to be sold will be zero.
Explanation
Solution
Since firm sells at $25 each for coats and pants, then If consumer wants to purchase both Pant and Coat, the customer will have to pay 25 + 25 = $50.
Also, If consumer purchase Pant and Coat as a Bundle then, he will pay 150. From the question stated we can conclude that their is a form of interest to pay for Pant and Coat for Both consumers are higher than 25.
However, they will have to pay an amount less for 1 coat and 1 pant if they buy this in a separate way instead of a Bundle.
We can say, that type of consumers (both) will not buy the pants and coat as a bundle, but will want to buy them separately.
Therefore, any bundle will not be sold by firm. the amount of Bundle sold will be known as a zero Bundle
