Question

find the amount and compound interest on rupees 5000 for 2 years at 6% per annum interest payable early

Answer 1

$here \: p = 5000 \\ n = 2 \\ r = 6 \\ so \: amount = 5000(1 + \frac{6}{100} ) ^{2} \\ = 5000 \times \frac{106}{100} \times \frac{106}{100} \\ = 5618 \\ and \: c. \: i. \: = 5618 - 5000 = 618$

Answer 2

Principal(P)  = Rs 5000

Rate of Interest(r )  = 6%

Time = 2 years

take n = 2 years.

A = P( 1 + r /100)^n  Where  A = Amount  and n = number of years

A = 5000* (1+6/100)^2

A = 5000 *(106/100)^2

A = 5000 * 11236/10000

A = Rs 5 * 11236/10

A = Rs 11236/2

A =5618

The Amount after two years = Rs 5618

C.I = A - P

C.I = Rs 5618 - Rs 5000 = Rs 618 ans
