2) N's work rate is twice that of M

Question: Which machine finished work earlier than the other machine?

Statement 1: Machine N can make 1,000 more units than M per hour
Case 1: N makes 2000 per hour and M makes 1000 per hour i.e. M takes 3 hours and N take 2 hours to finish their work
Case 2: N makes 4000 per hour and M makes 3000 per hour i.e. M takes 1 hours and N take 1 hours to finish their work
NOT SUFFICIENT

Statement 2: N's work rate is twice that of M

i.e. When N makes 4000 Products then M makes 2000 i.e. N always makes 4000 product in a time less than the time taken by M to make 3000 parts.
SUFFICIENT
