Explanation:
Given 9x + 11y = 304.
x = (304?11y)/9 = 33 + (7?2y)/9 + y
So y = - 1 satisfies. Now x = 35,
Now other solutions of this equation will be like this. Increase or decrease x by 11, decrease or increase y by 9. So we have to maximize x. next solution is x = 24 and y = 8. So bags required are 32.
