Pen & Paper ITrick brain teasers appear difficult at first, but they have a trick that makes them really easy.
You will need a working pen and a sheet of paper for this one. Orient the paper into landscape form, and write this on the paper:
620 = 3000
Your challenge: Add only two lines to make the equation valid.
Cross the equation sign to obtain a "not-equal" sign.
Fold the paper in any way.
Draw any curves.
Place any decimal points.
Place any middle dots (for multiplication).
Use "000" as a distinct number.
HintI am about 50% confident that this hint will help you.
AnswerDraw a slash between the 6 and the 20, and another slash between the second and third zeroes of the 3000.
You should have 6/20 = 30%.
