If Ben gives 10 post-it notes to Min, she will have 10 more post-it notes than him. However, Min must have 16 more post-it notes than Ben in the end. So, Ben has to give Min more post-it notes.
Number of more post-it notes that Ben has to give to Min
= (16 - 10) ÷ 2
= 6 ÷ 2
= 3
So after giving 10 post-it notes to Min, Ben has to give her another 3 more post-it notes so that she has 16 post-it notes more than him.
Total number of post-it notes that Min needs to get from Ben
= 10 + 3
= 13
Answer(s): 13
