এক ব্যক্তি সরল সুদে কিছু টাকা ধার নিল। 4 বছর পর। তিনি ঋণদাতাকে অর্থের \(\frac{9}{5}\) ফেরত দিয়েছেন।
সূত্র ব্যবহৃত:
সরল সুদ = P x R x T / 100 [ P = মূল, R = সুদের হার, T = সময়]
গণনা:
ধরুন, R = সুদের হার
প্রিন্সিপা হল = P
ব্যক্তি দ্বারা পাওয়া সহজ সুদ হয়
⇒ 9P/5 - P = 4P/5
সূত্র অনুযায়ী,
⇒ 4P/5 = P x 4 x R/100
⇒ R = 20%
∴ সঠিক বিকল্পটি হল 4
