Question

find the compound interest on rupees 8000 for 1 1/2 years at 10% per annum if interest being compounded half yearly​

Answer 1

Answer:

Principal = 8000

Rate=10%

Time=11/2

Compounded half yearly first we find the amount

A=P(1+R/200)2n

=8000(1+10/200)2×11/2

• =8000(200+10/200)11
• =8000×210/200×210/200×210/20 0×210/200×210/200×210/200×210/200×210/200×210/200×210/200×210/200
• A=13682.71
• Compound Interest=A-P
• =13682.72-8000
• =5682.72
• hence the amount is 13682.72 and compound half yearly Interest is 5682.72
