Correct Answer:
গ: ৪০ বছরে
Explanation:
কোনো আসল ২০ বছরে সুদে-মূলে দ্বিগুণ হলে কত বছরে সুদে-মূলে তিনগুণ হবে -- সঠিক উত্তর ৪০ বছরে ধরি, আসল = ১০০ সুদে - মূলে দ্বিগুণ = ১০০×২ = ২০০ সুদ = ২০০ - ১০০ = ১০০ আমরা জানি, হার = (১০০×সুদ)/(আসল × সময়) = (১০০×১০০)/(১০০×২০) = ৫% সুদে - মূলে তিনগুণ = ১০০×৩ = ৩০০ সুদ = ৩০০ - ১০০ = ২০০ আমরা জানি, সময় = (১০০ × সুদ)/(আসল × হার) = (১০০ × ১০০)/(১০০ × ৫) = ৪০ বছর

Correct Answer:
B: Tk. 51.25

Correct Answer:
A: Tk 25.00
Explanation:
Five years ago, Tk. 1,200 was deposited into a savings account paying 4.5% interest. Today, the balance in the account is Tk. 1,495. If interest paid on the account was compounded annually, how much interest on interest was earned? Correct Answer Tk 25.00 Sentence টি present Tense অনুসারে হবে। সুতরাং সঠিক উত্তর option (d), Subject plural হওয়ার কারণে এখানে verb ও plural হয়েছে অর্থাৎ have বসেছে। এবং recently adverb হিসেবে মূল verb এর আগে পরে বসতে পারে; তবে auxiliary verb ও মূল verb এর মাঝে adverb এর অবস্থান বেশি উপযোগী।
