Option 3: 1000 -> The money multiplier formula is 1/CRR = 1/0.20 = 5. Total money supply = Initial deposit × Money multiplier = ₹200 × 5 = ₹1000. When CRR is 20%, banks must keep 20% as reserves and can lend 80%. Through multiple rounds of deposits and lending, the initial deposit of ₹200 creates a total money supply of ₹1000 in the economy. -> correct
