প্রশ্নে বলা হচ্ছে যে, এক ব্যক্তি Interest এবং Wages থেকে 5,000 টাকা আয় করেছেন। যদি তিনি তার বিনিয়োগ দ্বিগুণ করেন এবং Wages যদি 50% বৃদ্ধি পায়, তবে তাঁর আয় দাঁড়ায় 8,000 টাকা। প্রশ্ন হল আলাদাভাবে Interest এবং Wages থেকে তার প্রকৃত আর কত ছিলো?

 

Let, interest x Tk.

Wages (5.000- x) Tk. 

According to question

2x+1.5(5,000-x)= 8,000⇒2x+7,500-1.5x = 8,000⇒0.5x = 8,000-7,500⇒ 0.5x = 500 ⇒x= 5000.5∴x=1,000 tk 

Interest 1,000 Tk.

Wages = 5,000-1,000= 4,000 Tk.

ans. The incomes from Interest and wages be Tk. 1,000 and Tk. 4,000 respectively.
