Question

find the compound interest on rupees 1000 10% per annum for 2 years

Answer 1

compound interest after 2yrs of 1000 Rs at the rate 10% per annum is 210 Rs.

it is given that principal , P = 1000 Rs.

rate of interest , r = 10% per annum

time duration, n = 2 yrs

using formula, C.I = P[(1 + r/100)ⁿ - 1]

= 1000[(1 + 10/100)² - 1]

= 1000[(1 + 1/10)² - 1]

= 1000[(1 + 0.1)² - 1]

= 1000[(1.1)² - 1]

= 1000[1.21 - 1]

= 1000 × 0.21

= 210 Rs.

hence, compound interest = 210 Rs.
