    Explanation

    Given that Mr. Kailash borrowed Rs. 40000 from a bank He takes loan at 10% compound interest per annum. When interest is compounded annually: Amount after t years =P(1+R100)t= P{\left( {1 + \frac{R}{{100}}} \right)^t} (where P = Principal, R = Rate% and t = years) Amount at the end of 1st year =40000(1+10100)1= 40000{\left( {1 + \frac{{10}}{{100}}} \right)^1} = 40000 × 11/10 = 44000 Amount to be paid after paying 1st installment = 44000 – 10000 = 34000 Amount at the end of the 2nd year =34000(1+10100)1= 34000{\left( {1 + \frac{{10}}{{100}}} \right)^1} = 34000 × 11/10 = 37400 Amount to be paid after paying 2nd installment = 37400 – 10000 = 27400 Amount at the end of 3rd year =27400(1+10100)1= 27400{\left( {1 + \frac{{10}}{{100}}} \right)^1} = 27400 × 11/10 = 30140 Amount to be paid after paying 3rd installment = 30140 – 10000 = 20140 Amount at the end of 4th year =20140(1+10100)1= 20140{\left( {1 + \frac{{10}}{{100}}} \right)^1} = 20140 × 11/10 = 22154 Amount to be paid at the end of 4th year to clear the lone = 22154
