One cake + one bun = 23p + 39p = 62p
512 ÷ 62 = 8 remainder 16, so buying 8 cakes and 8 buns costs 16p less
16 = 39 - 23 is the difference between them
So buy one more bun and one less cake
7 cakes and 9 buns

Lời giải:
Gọi số sách mà Clara đã mua là $a$ và số tạp chí đã mua là $b$ (\(a,b\in\mathbb{N}^*\) )
Theo bài ra ta có: \(3,4a+1,6b=23\)
\(\Rightarrow 3,4a=23-1,6b\leq 23-1,6.1\) do \(b\geq 1\)
hay \(3,4a\leq 21,4\Rightarrow a\leq \frac{21,4}{3,4}\Rightarrow a\leq 6\)
Vì \(a\in\mathbb{N}^*\Rightarrow a\in\left\{1;2;3;4;5;6\right\}\)
Nếu \(a=1\Rightarrow b=\frac{23-3,4}{1,6}=\frac{49}{4}\not\in\mathbb{N}^*\) (loại)
Nếu \(a=2\Rightarrow b=\frac{23-3,4.2}{1,6}=\frac{81}{8}\not\in\mathbb{N}^*\) (loại)
Nếu \(a=3\Rightarrow b=\frac{23-3,4.3}{1,6}=8\) (thỏa mãn)
Nếu \(a=4\Rightarrow b=\frac{23-3,4.4}{1,6}=\frac{47}{8}\not\in\mathbb{N}\) (loại)
Nếu \(a=5\Rightarrow b=\frac{23-3,4.5}{1,6}=\frac{15}{4}\not\in\mathbb{N}^*\) (loại)
Nếu \(a=6\Rightarrow b=\frac{23-3,4.6}{1,6}=\frac{13}{8}\not\in\mathbb{N}^*\) (loại )
Vậy Clara mua $3$ quyển sách và $8$ quyển tạp chí.
