ThinkTank #13 - Maths


Mr Lee had $1600. Did you get it correct?

To solve this problem, we need to understand that when the price of the TV was further reduced by 15%, Mr Lee ended up with $100 left instead of a shortage of $200. This means that 15% = $300 (the difference). Solving for 75% (the price of the TV after 25% discount) and adding the $100 that he had left would show that Mr Lee had $1600 all along.
