মূলধন = 12000 টাকা
সময় = 5 বছর
অনুসৃত সূত্র:
সুদ-আসল = মূলধন × (1 + r/100)n
গণনা:
সুদ-আসল = মূলধন × (1 + r/100)5
⇒ 24000 = 12000 × (1 + r/100)5
⇒ 24000/12000 = (1 + r/100)5
⇒ 2 = (1 + r/100)5 (1)
⇒ 15 বছর শেষে,
⇒ সুদ-আসল = 12000 × (1 + r/100)15
⇒ সুদ-আসল = 12000 × [(1 + r/100)5]3 (1 থেকে)
⇒12000 × 23
⇒12000 × 8
⇒ 96000
∴ 15 বছর শেষে সুদ-আসল হবে 96000 টাকা
