Hello sir ...I always watch your videos specially your rapid fire round videos. But in this video I have some doubt. In your first sentence your student translated that if you were my friend what would you do for me. But in third sentence your student translated that if I were rich I would have purchased Bangalore.. In both sentences she used 'were 'but in second part she used would in first sentence and would have used by her in second part of third sentence... What is basic difference in both sentences please clear it
