Azhar plans to visit the National Museum once each month in 2014 except in March and May when he plans to go three times each month. A single admission costs Tk 5.50, a pass valid for unlimited visits in any 3-month period can be purchased for Tk 27, and an annual pass costs Tk 80. What is the least amount that Azhar can spend for his intended number of visits?
Explanation: 3-month pass বছরে 4 বার নেওয়া হলে খরচ হবে \(27 \times 4 = 108\) taka. May to March এর মধ্যে সর্বমোট 7 বার যাওয়া হয়। সুতরাং এই 3 months এ 3-month pass নিয়ে বাকী সময় এর জন্য pay per visit package নিলে খরচ হয় \(27 + (5.5 \times 9) = 76.5\) taka which is less than 80 and 108 both.
