Find amount on 8000Rs @ 5%per annum for 3 years compounded yearly? |
|
Answer» Answer: PRINCIPAL for the first YEAR = Rs.8000, Rate = 5% per annum, T = 1 year INTEREST for the first year = =100P×R×T=Rs.[1008000×5×1]=Rs.400 ∴ Amount at the end of the first year = Rs. (8000 + 400) = Rs. 8400 Now principal for the second year = Rs.8400 Interest for the second year = 100P×R×T=Rs.[1008400×5×1]=Rs.420 ∴ Amount at the end of the second year = Rs. (8400 + 420) =Rs.8820 Interest for the third year = 100P×R×T=Rs.1008820×5×1=Rs.441 ∴ Amount at the end of the third year = Rs.(8820 + 441) = Rs. 9261 Now we know that total C.I. = Amount - Principal = Rs. (9261 - 8000) = Rs. 1261 we can also FIND the C.I. as follows Total C.I. = Interest for the first year + Interest for the second year + Interest for third year = Rs. (400 + 420 + 441) = Rs.1261 Step-by-step explanation: hope this helps mark me as brilliant |
