আসল= 20,000 টাকা।
সুদের হার (R) = 10% বার্ষিক
সুদ-আসল = 26,620 টাকা।
সময় = n বছর
অনুসৃত সূত্র :
সুদ-আসল= আসলx {1 + \(\frac{R}{100}\) } সময়
গণনা:
প্রশ্ন অনুযায়ী,
সুদ-আসল=আসল x {1 + \(\frac{R}{100}\) } সময়
⇒ 26,620 = 20,000 x {1 + \(\frac{10}{100}\) } n
⇒ \(\frac{26,620}{20,000}\) = {1 + \(\frac{1}{10}\) } n
⇒ \(\frac{1331}{1000}\) = { \(\frac{11}{10}\) } n
⇒ ( \(\frac{11}{10}\) )³ = ( \(\frac{11}{10}\) ) n
⇒ n = 3
সুতরাং, n বছরের প্রয়োজনীয় মান হল 3 বছর
