Gọi số bé là ab, ta có:
\(\overline{ab}+\overline{ab25}=5883\)
\(\Leftrightarrow\overline{ab}+\overline{ab00}+25=5883\)
\(\Leftrightarrow\overline{ab}+\overline{ab00}=5858\)
\(\Leftrightarrow\overline{ab}\times1+\overline{ab}\times100=5858\)
\(\Leftrightarrow\overline{ab}\times\left(1+100\right)=5858\)
\(\Leftrightarrow\overline{ab}\times101=5858\)
\(\Rightarrow\overline{ab}=5858\div101=58\)
\(\Rightarrow\overline{ab25}=5825\)
Vậy...........
