Prompt:
Total production = 1000n
Statement 1:
Total production for the first 5 days = 5*600 = 3000
Statement 2:
Total production for the last 4 days = 4*1500 = 6000

Case 1: n=9, with no days between the first 5 days and the last 4 days
Total production = 1000n = 1000*9 = 9000
Total production = (production for the first 5 days) + (production for the last 4 days) = 3000+6000 = 9000

Case 2: n=10, with one 1000-tool day between the first 5 days and the last 4 days
Total production = 1000n = 1000*10 = 10000
Total production = (production for the first 5 days) + (production for one 1000-tool middle day) + (production for the last 4 days) = 3000+1000+6000 = 10000

Since n can be different values, the two statements combined are INSUFFICIENT.

The correct answer is E.
