If Vaidev gives 5 bookmarks to Gillian, she will have 5 more bookmarks than him. However, Gillian must have 17 more bookmarks than Vaidev in the end. So, Vaidev has to give Gillian more bookmarks.
Number of more bookmarks that Vaidev has to give to Gillian
= (17 - 5) ÷ 2
= 12 ÷ 2
= 6
So after giving 5 bookmarks to Gillian, Vaidev has to give her another 6 more bookmarks so that she has 17 bookmarks more than him.
Total number of bookmarks that Gillian needs to get from Vaidev
= 5 + 6
= 11
Answer(s): 11
