Thomas has three times as many stickers as John

Question

Thomas has three times as many stickers as john. How many stickers must Thomas give John so that they each will have 150 stickers.

Answer 1

Let's say John has x stickers; then Thomas must have 3x of them and that is a total 4x.

 

If John gets x stickers from Thomas then each will have 2x, and if that equals 150, x must equal 75.

 

Thomas must hand over 75 stickers to equalize their individual holdings.
