Solution:The definition of Reverse repo rate, "it is the interest rate paid by RBI to its clients for short term loans." Repo rate is the rate RBI charges on its clients for short term loans. Clients of RBI are such as the Central Government, State Government, Banks (commercial, regional rural banks, cooperative banks) and Non-banking financial institutions, etc.
The reverse repo rate is 100 basis points lower than the repo rate. In other words, Repo rate = reverse repo + 1%. So the gap in the recent past is not 'declining'. The gap is fixed at 1%=> statement 3 is incorrect.
