Assuming that Xiao Nan and Fang Fang took out x books at the same time, their total number would add up to 30+x. Since Fang Fang had 54-30=24 more books than Nan, the number of books Fang Fang took out must be a multiple of x+24. And because the number that Xiao Nan takes out must be a multiple of x, we can write the following equation: (x+24) = 30 By solving this equation, one could obtain: x = 30 - 24 = 4 Therefore, Nan and Fangfang took out four extra books at the same time. The total number of books they had was 30+4=34, which was exactly Fangfang's number of books plus 24.
