GIVEN:
Principal = Rs. 6000
Rate of Compound Interest = 8%
FORMULA USED:
Amount left after each Installment = P(1 + (R/100)) – Monthly installment
CALCULATION:
Amount left after 1st installment = 6000(1 + (8/100)) – 1500 = 6480 – 1500 = 4980
Amount left to pay after 2nd installment = 4980(1 + (8/100)) – 1500 = 5378.4 – 1500 = 3878.4
Amount left to pay after 3rd installment = 3878.4(1 + (8/100)) – 1500 = 4188.672 – 1500 = 2688.672
Amount left to pay after 4th installment = 2688.672(1 + (8/100)) – 1500 = 2903.765 – 1500 = 1403.765
∴ Amount left to be paid = Rs. 1403.765

A person borrows Rs. 6000 from a co-operative bank at 8% compound inte...
Given:
- Principal amount (P) = Rs. 6000
- Rate of interest (R) = 8% or 0.08 (as a decimal)
- Amount paid at the end of every year (A) = Rs. 1500
To find:
The amount still owed to the co-operative bank after four installments.
Solution:
1. Calculation of Interest:
The interest for the first year can be calculated using the compound interest formula:
I = P(1 + R)^n - P
where I is the interest, P is the principal amount, R is the rate of interest, and n is the number of years.
Substituting the given values:
I1 = 6000(1 + 0.08) - 6000
I1 = 480
Similarly, the interest for the second, third, and fourth years can be calculated as:
I2 = (6000 - A)(1 + R) - (6000 - A)
I3 = (6000 - 2A)(1 + R) - (6000 - 2A)
I4 = (6000 - 3A)(1 + R) - (6000 - 3A)
2. Calculation of Remaining Loan Amount:
The remaining loan amount after the first year is:
Loan1 = P + I1 - A
Loan1 = 6000 + 480 - 1500
Loan1 = 4500
Similarly, the remaining loan amount after the second, third, and fourth years can be calculated as:
Loan2 = Loan1 + I2 - A
Loan3 = Loan2 + I3 - A
Loan4 = Loan3 + I4 - A
3. Calculation:
Substituting the calculated values:
Loan2 = 4500 + (6000 - 1500)(1 + 0.08) - (6000 - 1500)
Loan2 = 4500 + 360 - 4500
Loan2 = 4860
Loan3 = 4860 + (6000 - 2 * 1500)(1 + 0.08) - (6000 - 2 * 1500)
Loan3 = 4860 + 240 - 4500
Loan3 = 2760
Loan4 = 2760 + (6000 - 3 * 1500)(1 + 0.08) - (6000 - 3 * 1500)
Loan4 = 2760 + 120 - 4500
Loan4 = 1380
Therefore, the person still owes Rs. 1380 to the co-operative bank after four installments.
