Gộp các tờ loại \(2000\)đồng và loại \(1000\)đồng lại thành một tờ mới. 

Mệnh giá tờ mới là: 

\(\left(2000\times2+1000\times1\right)\div\left(2+1\right)=\frac{5000}{3}\)(đồng) 

Giả sử tất cả các tờ đều là tờ loại mới. Khi đó tổng số tiền thu được là: 

\(\frac{5000}{3}\times145=\frac{725000}{3}\)(đồng) 

Số tờ loại \(5000\)đồng là: 

\(\left(315000-\frac{725000}{3}\right)\div\left(5000-\frac{5000}{3}\right)=22\)(tờ) 

Số tờ loại mới là: 

\(145-22=123\)(tờ) 

Nếu số tờ loại \(2000\)đồng là \(2\)phần thì số tờ loại \(1000\)đồng là \(1\)phần.

Số tờ loại \(2000\)đồng là: 

\(123\div\left(2+1\right)\times2=82\)(tờ) 

Số tờ loại \(1000\)đồng là: 

\(123-82=41\)(tờ)
