The price of sugar has increased by 32%. A family reduces its consumption so that the expenditure of sugar is up by 10% only. If the total consumption of sugar before the price rise was 10 kg per month, what is the current consumption of sugar per month (in kg)?
Explanation: মনে করি, previous price of sugar \(= Tk. 100\) per kg. 32% বৃদ্ধি পাবার পরে price হয় \(= Tk. 132\). Previous consumption of sugar was \(10 kg\). Therefore, previous expense \(= 100\times10 = Tk. 1000\). Current expenditure কে 10% বৃদ্ধিতে আবদ্ধ করতে গেলে তা হবে \(= 1000\times1.10 = Tk. 1100\). Therefore, current consumption \(= 1100/132 \approx 8.33\) kg.
