Solution: একটি Item এর Price প্রথমে যদি 10% বাড়ে এবং পরে 10% কমে, তাহলে Price এর Net effect কি হবে ? Shortcut: A + B + = 10 + 10 + = -1 [ a decrease of 1% ] ধরি, Item টির মূল্য ছিল = 100 টাকা 10% বাড়লে মূল্য হয় = 100 + 100 = 110 টাকা আবার, 10% কমলে মূল্য হয় = 110 - 100 = 99 টাকা অর্থাৎ মূল্যের Net effect = 100 - 99 = 1% কমবে ।Related questions
