If the price of onion is decreased by 60%, find by how much percent a man must increase his consumption of onion so that the expenditure on onion remains same ?
Solution
Correct Answer: Option D
Solution:
অনুবাদঃ পেঁয়াজের মূল্য 60% কমায় একজন ব্যক্তি পেঁয়াজের ব্যবহার কতটুকু বাড়ালে তার পেঁয়াজের উপর মোট খরচ
অপরিবর্তিত থাকবে ?
সূত্রঃ Increase in consumption = \(\frac{{\% \Pr ice decrease}}{{100 - \% \Pr ice decrease}} \times 100\)
So Increase in consumption = \(\frac{{60 \times 100}}{{100 - 60}}\)
= 150%
