Question

At what rate percent will a sum of rupress 3125 amount to ruppes 3645 in two years?

Answer 1

=> interest got in 2 years = amount -
principal

= 3645 -3125

= 520

=> simple interest = principal × rate% × time /100

=> 520 = 3125 × rate % × 2 /100

=> 520 /3125 × 100 /2 = rate %

=> rate % = 8.32




the rate of interest is 8.32% per annum
