Question

Henna borrowed $ 20000 from her friend Nancy at 12% per annum simple Interest. She lent it to Andy at the same rate but compounded annually. Find her gain after 2 years. 

Answer 1

Answer:

d = Rs 288

Step-by-step explanation:

/* We know that ,

If on a certain sum "P" , difference between compound interest and simple interest is 'd' and rate percentage is R% for 2 years , then the relation is

d = P\left(\frac{R}{100}\right)^{2}

Where d = (CI - SI ) for 2 years */

Here,

Principal (P) = Rs 20000,

R = 12%,

d = 20000\left(\frac{12}{100}\right)^{2}

= 20000\times \frac{12}{100}\times \frac{12}{100}

= 2\times 144\\=Rs 288
