I am putting up the Question of the day series on my Youtube channel " The logicalist". Do visit this channel and based on your feedbacks we will try to improve it further. Puzzles will come up as a full fledged course on this platform.
Try this question : An article was sold at 20% profit. Had it been purchased at Rs 900 less and sold at Rs 900 less, the profit would have been 30%. What is the original price at which the article was sold?
