Question

Harpreet borrowed * 20000 from her friend at 12% per annum simple interest. She lent it
to Alam at the same rate but compounded annually. Find her gain after 2 years.​

Answer 1

Answer:

principal=2000

rate=12percent

A=P(1+r/100)^t

A=2000(112/100) ²

A=2508.8

CI=508.8

SI=2000*12*2/100

SI=480

profit=28.8

Step-by-step explanation:

principal is rupees 2000 and rate of interest is 12 percent so the simple interest for Harpreet will be rupees 480(for two years).Then she lent it to Alam at 12 percent per annum compounded annually for two years so CI for the same will be 508.8 rupees then we will subtract SI from CI to calculate her profit which will come 28.8 rupees.
