A restaurant meal had cost Tk 35.50 and there was no tax. If the service charge was more than 10 percent but less than 15 percent of the cost of the meal, then the total amount paid must have been between Tk -
Explanation: Restaurant এ বিল আসলো 35.50 taka. যদি 10% Tax হয় তবে bill amount হবে \((35.50 \times 1.10) taka = 39.05\) taka. যদি 15% Tax হয় তবে bill amount হবে \((35.50 \times 1.15) taka = 40.825\) taka. সুতরাং যদি 10% থেকে 15% এর মধ্যে Tax হয় তবে bill amount 39.05 taka থেকে 40.825 taka হবে যা 39 এবং 41 এর মধ্যে।
