If Zane gives 11 stickers to Yoko, she will have 11 more stickers than him. However, Yoko must have 17 more stickers than Zane in the end. So, Zane has to give Yoko more stickers.
Number of more stickers that Zane has to give to Yoko
= (17 - 11) ÷ 2
= 6 ÷ 2
= 3
So after giving 11 stickers to Yoko, Zane has to give her another 3 more stickers so that she has 17 stickers more than him.
Total number of stickers that Yoko needs to get from Zane
= 11 + 3
= 14
Answer(s): 14
