Consider the join operation between relation r and s ( sθ  r ),  θ  is  r.A = s.B with the following information: Relation r contains 6,000 tuples and has 12 tuples per block. Relation s contains 5,000 tuples and has 5 tuples per block. There are 33 buffer blocks available in Memory. V(A, r) = 6,000 and V(B, s) = 5,000.          Find total cost (the number of block transfers) using Nested Loop Join =
