Think of the original sum of money as 9u.

4 books cost 2u
So 8 books cost : 2u × 2 = 4u

Remaining money = 9u - 2u = 7u

7u can buy 8 books and 2 bags.

Since 8 books cost 4u,

Cost of 2 bags = 7u - 4u = 3u

Original sum of money = 9u, so that is enough to buy 6 bags

(9u ÷ 3u = 3
3 × 2 bags = 6 bags)
