    Solution

    ATQ,

    Compound interest received = 12000 Γ— {1 + (10/100)}Β² βˆ’ 12000

    = 12000 Γ— 1.10Β² βˆ’ 12000

    = 12000 Γ— 1.21 βˆ’ 12000

    = Rs. 14,520 βˆ’ 12,000 = Rs. 2,520

    Simple interest received = 9000 Γ— 4 Γ— 13 Γ· 100= 9000 Γ— 0.52 = Rs. 4,680

    So, required difference = 4680 βˆ’ 2520 = Rs. 2,160
