బారు వడ్డీ = (P × R × T)/100, ఇక్కడ P అనేది అసలు, R వడ్డీ రేటు మరియు T అనేది కాల వ్యవధి.

చక్ర వడ్డీ =  [P (1 + R/100)n] - P, ఇక్కడ P  అనేది అసలు, R వడ్డీ రేటు మరియు n కాల వ్యవధి.

SI = (4500 × 8 × 3) / 100 = రూ. 1080

⇒ CI = [4500 (1 + 8/100) 3] - 4500 = రూ. 5668.7 - 4500 = 1168.7

∴ అవసరమైన వ్యత్యాసం = రూ. 88.70
