People ask where would AAP get money from to fulfill their promises. Remember that episode on Garbage on Satyamev Jayate where a scientist explained how a work that could have been easily done in 3 crores was done in 70 crores using a different mechanism and that too a much substandard work.
Can the highlighted words be replaced by could be, such that it does not change the tense.
Are "could have been" and "could be" interchangeable?
