Can i see your working pls? Thanks
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)
